Lock objects to text

Does anyone know of a way to lock floating objects to text in a Pages09 document? I love the way Pages deals with floating objects, so much better than Word, but I'd like to be able to lock individual or grouped objects (images, text boxes) to a specific paragraph, so they move together during editing. I see how to lock objects to a specific location on a page, but this is not what I want.

What you are requesting is called an anchor and it is a feature that I too wish Pages had. For now, if you want an object to flow with our edited text, the only choice is an inline object. However I have found that either Pages 09 has better inline text wrapping or I totally missed that Pages 08 got it. Try placing an object inline, setting its text wrapping to on, and then play with the options. You might find that you can get what you want this way.
I'm in the midst of creating a large set of tutorials with lots of pictures of menus, palettes, and the like. Each tutorial is from 5 to 12 pages long. Even though I'm not getting the exact placement I want using this method, it is close enough for me to use while I'm writing and editing. When I'm finished with a tutorial I've been going back and making some of them floating objects again and tweaking their locations a bit. A bit of a kludge but we work with what we've got, eh?

Lock objects

Hi experts,
My requirement is to create lock for parent table and its child tables.Each and every child tables is having relation with the parent table.
When iam creating the lock for parent table, in this process iam adding the child tables in the list.But here one child table is missing in the log eventhough its having the relation with parent table.
Valuable replies will be awarded with points.........

Hi,
it may help u
1) Select object type Lock object in the initial screen of the ABAP Dictionary, enter an object name and choose Create. The name of a lock object should begin with an E (Enqueue).The maintenance screen for lock objects is displayed.
2) Enter an explanatory short text in the field Short text. You can then use the short text to find the lock object at a later time, for example with the R/3 Repository Information System.
3) Enter the name of the primary table of the lock object. All other tables in the lock object must be linked with the primary table using foreign keys.
4) Select the lock mode of the primary table in the field below it The lock mode is used as the default value for the corresponding parameters of the function modules generated from the lock object.
5) Choose Add if you want to lock records in more than one
table with the lock object. A list of all the tables linked with the primary table using valid foreign keys is displayed. Select the appropriate table. The lock
mode of the primary table is copied as lock mode. You can change this setting as required, for example you can assign the lock mode separately for each table.
Similarly, you can add a table linked with the secondary table just added with foreign keys. To do this, place the cursor on the name of the secondary table and choose Add.
If no lock mode is assigned to a table, no lock is set for the
entries in this table when the generated function modules are
called. You should not assign a lock mode if a secondary table
was only used to define a path between the primary table and
another secondary table with foreign keys.
6) Save your entries.
A dialog box appears in which you have to assign the lock
object a development class.
7) You can define whether the function modules generated from
the lock object should be RFC-enabled on the Attributes tab
page. If you set the Allow RFC flag, the generated function
modules can be called from within another system with Remote
Function Call. If you permit Remote Function Calls for an
existing lock object, you must ensure that the generated
function modules are called from within an ABAP program with
parameters appropriate for the type. You should therefore check
all programs that use the associated function modules before
activating the lock object with the new option.

Can i use the SAP standard package for lock object creation ?

Dear Guru ,
I want to create a new lock ojbect for my abap program .
When i completed the creation , SAP required a new request and it said the object only can be imported to SAP standard package .
But i saw the help from SAP said :
>* Package begins with A-S or U-X:
>These packages are for SAP standard objects. Customer objects cannot be created in them. Changes to objects of these packages are recorded by the Transport Organizer (Request management) and can be transported (see field transport layer.
In this case , Can i use one of the SAP standard package for this creation ? Does it will affect the SAP system ( such as the system upgrade ) ?
Thanks .
Best Regards,
Carlos Zhang

Hi Carlos...
First , You will never be able to use any standard SAP Package for your custom programs. So don't go for it.
So in your case what you need to do is , when you save your Lock object ,
- if you want Transport request to be created , then
in the screen shown you need to enter the Z package name (the same package as that of your ABAP Program)
or
-if you want it to be stored as local object , then
specify package as $tmp

Lock Object Creation

Hi,
Is it possible to create lock objects at runtime? if not, how do I lock tables at runtime when the table name is specified in the selection screen by the user?
Thanks.
Tyken

Hi tyken,
Try this.
Lock Objects are Created using Tcode SE11.
The Lock object name must be start with EZur name.
Mainly lock objects are used for locking the transactions, tables --etec.
Multiple users can not updated the same transaction at the same time.
Whenever u create a lock object using se11. SAP internally
creates a two function modules:
Enqueue_lockobjname ---For Locking purpose,
dequeue_lockobjname---For Unlocking purpose.
U make use of these fms to lock and unlock transctions, tables..etc.
Steps to create lock objects :
GO TO SE11
Select the radio button "Lock object"..
Give the name starts with EZ or EY..
Example: EYTEST
Press Create button..
Give the short description..
Example: Lock object for table ZTABLE..
In the tables tab..Give the table name..
Example: ZTABLE
Save and generate..
Your lock object is now created..You can see the LOCK MODULES..
In the menu ..GOTO -> LOCK MODULES..There you can see the ENQUEUE and DEQUEUE function
The example is as follws:
EPORT ZLOCK_UNLOCK
MESSAGE-ID ZBDC.
TABLES ZSTUD.
DATA text(8) TYPE c.
CALL SCREEN 100.
*& Module USER_COMMAND_0100 INPUT
text
MODULE USER_COMMAND_0100 INPUT.
CASE SY-UCOMM.
WHEN 'SELECT'.
SELECT SINGLE * FROM ZSTUD WHERE ROLLNO = ZSTUD-ROLLNO.
MESSAGE i004 WITH 'SY-SUBRC:' sy-subrc.
WHEN 'EXIT'.
LEAVE PROGRAM.
WHEN 'ENQUEUE'.
CALL FUNCTION 'ENQUEUE_EZLOCK1'
EXPORTING
MODE_ZSTUD = 'X'
ROLLNO = ZSTUD-ROLLNO
EXCEPTIONS
FOREIGN_LOCK = 1
SYSTEM_FAILURE = 2
OTHERS = 3.
CASE sy-subrc.
WHEN 0.
MESSAGE i004 WITH 'Enqueue successful'(001).
WHEN 1.
text = sy-msgv1.
MESSAGE e004 WITH 'Record already'(002) 'locked by'(003)
text.
CALL TRANSACTION 'SM12'.
WHEN 2 OR 3.
MESSAGE e004 WITH 'Error in enqueue!'(004)
'SY-SUBRC:' sy-subrc.
ENDCASE.
WHEN 'DEQUEUE'.
CALL FUNCTION 'DEQUEUE_EZLOCK1'
EXPORTING
MODE_ZSTUD = 'X'
ROLLNO = ZSTUD-ROLLNO
EXCEPTIONS
OTHERS = 1.
CASE sy-subrc.
WHEN 0.
MESSAGE i004 WITH 'Dequeue successful'(005).
WHEN 1.
MESSAGE e004 WITH 'Error in dequeue!'(006).
ENDCASE.
WHEN 'SM12'.

How to create a lock object in se11

hi all,
Can anyone tell me the step by step procedure to lock as well as unlock a particular object in se11 trns code. with an real time example.
thanxs in advance

Hi,
Lock objects are use in SAP to avoid the inconsistancy at the time of data is being insert/change into database.
SAP Provide three type of Lock objects.
- Read Lock(Shared Locked)
protects read access to an object. The read lock allows other transactions read access but not write access to
the locked area of the table
- Write Lock(exclusive lock)
protects write access to an object. The write lock allows other transactions neither read nor write access to
the locked area of the table.
- Enhanced write lock (exclusive lock without cumulating)
works like a write lock except that the enhanced write lock also protects from further accesses from the
same transaction.
You can create a lock on a object of SAP thorugh transaction SE11 and enter any meaningful name start with EZ Example EZTEST_LOCK.
Use: you can see in almost all transaction when you are open an object in Change mode SAP could not allow to any other user to open the same object in change mode.
Example: in HR when we are enter a personal number in master data maintainance screen SAP can't allow to any other user to use same personal number for changes.
Technicaly:
When you create a lock object System automatically creat two function module.
1. ENQUEUE_<Lockobject name>. to insert the object in a queue.
2. DEQUEUE_<Lockobject name>. To remove the object is being queued through above FM.
You have to use these function module in your program.
Creating Lock Objects
Procedure
1.Select object type Lock object in the initial screen of the ABAP Dictionary, enter an object name and choose Create. The name of a lock object should begin with an E (Enqueue).
The maintenance screen for lock objects is displayed.
2.Enter an explanatory short text in the field Short text.
You can then use the short text to find the lock object at a later time, for example with the R/3 Repository Information System.
3.Enter the name of the primary table of the lock object.
All other tables in the lock object must be linked with the primary table using foreign keys. There are also some restrictions on the valid foreign key relationships.
4.Select the lock mode of the primary table in the field below it.
The lock mode is used as the default value for the corresponding parameters of the function modules generated from the lock object.
5.Choose Add if you want to lock records in more than one table with the lock object.
A list of all the tables linked with the primary table using valid foreign keys is displayed. Select the appropriate table. The lock mode of the primary table is copied as lock mode. You can change this setting as required, for example you can assign the lock mode separately for each table.
6.Similarly, you can add a table linked with the secondary table just added with foreign keys. To do this, place the cursor on the name of the secondary table and choose Add.
7.If no lock mode is assigned to a table, no lock is set for the entries in this table when the generated function modules are called. You should not assign a lock mode if a secondary table was only used to define a path between the primary table and another secondary table with foreign keys.
8.Save your entries.
A dialog box appears in which you have to assign the lock object a development class.
9.You can (optionally) exclude lock parameters (see lock objects) from the function module generation on the Lock parameter tab page. This makes sense for example if you always want to lock a parameter generically.
To do this, simply deselect the Weight flag for the parameter. The parameter is not taken into consideration in the generated function modules. This parameter is then always locked generically.
9.The name of a lock parameter is usually the name of the corresponding table field. If two fields with the same name are used as lock parameters in the lock object from different tables, you must choose a new name for one of the fields in field Lock parameter.
10.You can define whether the function modules generated from the lock object should be RFC-enabled on the Attributes tab page.
If you set the Allow RFC flag, the generated function modules can be called from within another system with Remote Function Call.
11.If you permit Remote Function Calls for an existing lock object, you must ensure that the generated function modules are called from within an ABAP program with parameters appropriate for the type. You should therefore check all programs that use the associated function modules before activating the lock object with the new option.
12 .Choose Activate .
Result
When you activate the lock object, the two function modules ENQUEUE_<lockobjectname> and DEQUEUE_<lockobjectname> are generated from its definition to set and release locks.
You can find information about the activation flow in the activation log, which you can display with Utilities Activation log. If errors occurred during activation, the activation log is displayed immediately.
Pls reward points.

Lock objects are used to synchronize access to the same data by more than one program.
General information about the lock mechanism.
You can synchronize access by several programs to the same data with a logical lock mechanism. This lock mechanism fulfills two main functions:
A program can tell other programs which data records it is just reading or changing.
A program can prevent itself from reading data that is just being changed by another program.
When accessing data records, the records just being edited by other programs can be identified by the entry in the lock table. Such an entry for the lock must define a number of fully specified key fields, that is either a value is passed for the key field or this field is locked generically.
To set locks, a lock object must be defined in the ABAP Dictionary. When this lock object is activated, two function modules (see Function Modules for Lock Requests) are generated with the names ENQUEUE_<lockobjectname> and DEQUEUE_<lockobjectname>.
If data records are to be locked, you must call function module ENQUEUE_<lockobjectname>. The values of the key fields that specify the records to be locked are passed for all the tables contained in the lock object when the function module is called. There is a generic lock if a value is not passed for all the key fields. The function module writes the appropriate lock entry (see Example for Lock Objects). If another program also requests a lock, it will be accepted or rejected depending on the lock mode (see Lock Collisions). The program can then react to this situation.
Locked data records can be unlocked by calling function module DEQUEUE_<lockobjectname>. The key values and the lock mode used to set the lock must be passed to the function module.

Select object type Lock object in the initial screen of the ABAP Dictionary, enter an object name and choose Create. The name of a lock object should begin with an E (Enqueue).

Let me know creation of lock object

let me know creation of lock object

Hi
Lock Objects
Lock object concept
Lock modes
Creating a lock object (example)
Lock object sample code
SAP data dictionary provides you with a locking mechanism to synchronize simultaneous data access by different users.
Lock objects are created in SE11.
Customer lock objects must begin with EY or EZ .
Three possible lock modes exist for lock objects.
Lock Mode
Lock mode E: This sets a lock for changing data for single user. This lock can be accumulated.
Lock mode X: This mode is used like mode E for changing data. The only technical difference from mode E is that the respective lock does not allow accumulation.
Lock mode S: This mode ensures that data displayed in your program cannot be changed by other users during the entire display time. Here you do not want to change the data yourself (allows read only access for data).
Creating Lock object
SE11
1)Enter lock object name beginning with EY or EZ
and hit create.
2)Enter table names containing data records that should be locked and the lock mode.
Enter short text /tbale/lockmode.
3) The primary keys of the specified tables are automatically selected as lock parameters.
It automatically selects the primary key for the selected table.
To set a lock in the application program
call a function module ENQUEUE_<LOCK_OBJECT>.
For our example, it would be ENQUEUE_EZMARA.
To release the lock in the application program
call a function module DEQUEUE_<LOCK_OBJECT>.
For our example, it would be DEQUEUE_EZMARA.
Refer the code executed by user (say abap1) for
matnr = 000000000000000012.
Lock Objects are used to synchronize access to the same data by more than one user. Function modules that can be used in application programs are generated from the definition of a lock object in the ABAP Dictionary.
The R/3 System synchronizes simultaneous access of several users to the same data records with a lock mechanism. When interactive transactions are programmed, locks are set and released by calling function modules .These function modules are automatically generated from the definition of lock objects in the ABAP Dictionary.
Structure of a Lock Object
The tables in which data records should be locked with a lock request are defined in a lock object together with their key fields.
When tables are selected, one table (the primary table) is first selected. Further tables (secondary tables) can also be added using foreign key relationships.
Lock Arguments
The lock argument of a table in the lock object consists of the key fields of the table.
The lock argument fields of a lock object are used as input parameters in the function modules for setting and removing locks generated from the lock object definition. When these function modules are called, the table rows to be locked or
unlocked are specified by defining certain values in these fields.These values can also be generic. The lock argument fields therefore define which subset of the table rows should be locked
Data Dictionary/ Lock Objects
The simplest case of a lock object consists of exactly one table and the lock argument of the table is the primary key of this table. Several tables can also be included in a lock object. A lock request therefore can lock an entire logical
object, and not only a record of a table. Such a logical object can be for example a document comprising an entry in a header table and N entries in a positiontable.
Lock Mode
The lock mode controls whether several users can access data records at the same time. The lock mode can be assigned separately for each table in the lock object. When the lock is set, the corresponding lock entry is stored in the
lock table of the system for each table. Access by more than one user can be synchronized in the
following ways:
Exclusive lock: The locked data can only be displayed or
edited by a single user. A request for another exclusive lock
or for a
shared lock is rejected.
Shared lock: More than one user can access the locked data
at the same time in display mode. A request for another
shared lock is accepted, even if it comes from another user. An exclusive lock
is rejected. Exclusive but not cumulative: Exclusive locks can be requested
several times from the same transaction and are processed
successively. In contrast, exclusive but not cumulative locks
can be called only once from the same transaction. All other
lock requests are rejected.
1) Select object type Lock object in the initial screen of the ABAP Dictionary, enter an object name and choose Create. The name of a lock object should begin with an E (Enqueue).The maintenance screen for lock objects is displayed.
2) Enter an explanatory short text in the field Short text. You can then use the short text to find the lock object at a later time, for example with the R/3 Repository Information System.
3) Enter the name of the primary table of the lock object. All other tables in the lock object must be linked with the primary table using foreign keys.
4) Select the lock mode of the primary table in the field below it The lock mode is used as the default value for the corresponding parameters of the function modules generated from the lock object.
5) Choose Add if you want to lock records in more than one
table with the lock object. A list of all the tables linked with the primary table using valid foreign keys is displayed. Select the appropriate table. The lock
mode of the primary table is copied as lock mode. You can change this setting as required, for example you can assign the lock mode separately for each table.
Similarly, you can add a table linked with the secondary table just added with foreign keys. To do this, place the cursor on the name of the secondary table and choose Add.
If no lock mode is assigned to a table, no lock is set for the
entries in this table when the generated function modules are
called. You should not assign a lock mode if a secondary table
was only used to define a path between the primary table and
another secondary table with foreign keys.
6) Save your entries.
A dialog box appears in which you have to assign the lock
object a development class.
7) You can define whether the function modules generated from
the lock object should be RFC-enabled on the Attributes tab
page. If you set the Allow RFC flag, the generated function
modules can be called from within another system with Remote
Function Call. If you permit Remote Function Calls for an
existing lock object, you must ensure that the generated
function modules are called from within an ABAP program with
parameters appropriate for the type. You should therefore check
all programs that use the associated function modules before
activating the lock object with the new option.

What is the use for lock object and how to use the lock objects

Hi Guru's,
I am new to ABAP .Can you please clarify the that what is the use of lock object and how to use the loct object .what is use of the Deque & Enque function modules .

hi ,
below are some minfo about lock objects :
Lock Objects
These types of objects are used for locking the access to database records in table. This mechanism is used to enforce data integrity that is two users cannot update the same data at the same time. With lock objects you can lock table-field or whole table.
In a system where many users can access the same data, it becomes necessary to control the access to the data. In R/3 system this access control is built-in on database tables. Developers can also lock objects over table records.
To lock an object you need to call standard functions, which are automatically generated while defining the lock object in ABAP/4 dictionary. This locking system is independent of the locking mechanism used by the R/3 system. This mechanism also defines LUW i.e. Logical Unit of Work. Whenever an object is locked, either by in built locking mechanism or by function modules, it creates corresponding entry in global system table i.e. table is locked. The system automatically releases the lock at the end of transaction. The LUW starts when a lock entry is created in the system table and ends when the lock is released.
Creating Lock Objects
Lock object is an aggregated dictionary object and can be defined by using the following steps:
o From initial data dictionary screen, enter the name for the object, Click Lock object radiobutton and then click on Create. The system displays a dialog box for Maintain Lock Objects screen
o Enter short text as usual and the name for primary table.
-Save
-Select Tables option
From this screen you can:
Select secondary tables, if any, linked by foreign key relationship.
Fields for the lock objects. This option allows you to select fields for objects (R/3 system allows locking up to record level). Lock object argument are not selected by user but are imposed by the system and includes all the primary keys for the table.
1) Exclusive lock: The locked data can only be displayed or edited by a single user. A request for another exclusive lock or for a shared lock is rejected.
2) Shared lock: More than one user can access the locked data at the same time in display mode. A request for another shared lock is accepted, even if it comes from another user. An exclusive lock is rejected.
3) Exclusive but not cumulative: Exclusive locks can be requested several times from the same transaction and are processed successively. In contrast, exclusive but not cumulative locks can be called only once from the same transaction. All other lock requests are rejected.
Also, last but not the least, locking the object is logical (locking with any enqueue ) .so, you have to use the lock object while trying to access from second program .

The object R3TR TEXT OCS,EFP56A,STAM,D cannot be put in a reques

Hi,
When i am saving the configuration request in for new output type its give the below message.
Action cancel.
The object R3TR TEXT OCS,EFP56A,STAM,D cannot be put in a request
Message no. SV162
Can anyone give any input on this ....
Thanks
Vikrant

I guess it is a problem with locking, may the object is already locked (in a different request).
I think it is include LSVIMF1Z which issues the message. this include has 43 different reasons for an error. You have to debug to find the root cause.

Lock object is not working automatically

Hi experts,
i have a problem , A table is updated by a program which is used by multiple user . I have used lock function module 'ENQUEUE_E_TABLE ' and 'DEQUEUE_E_TABLE' for that . when updation section occurs first user which come first go through it and for rest users amessage cones 'table is locked by XYZ user' . When first completes the updation resr users is not updating automatically they stand at that position where message comes. How to solve this issue?

Hi,
We can lock the table before updating the entries. Two types of locks are there.
1. To lock the entire table. Here when the table is locked by one program, another program will not be able to modify it.
2. To lock the particular record only. Here when the record is locked by one program, the other program can modify records other than the one locked.
For option 1
Use the FM ENQUEUE_E_TABLEE to lock the table and FM DEQUEUE_E_TABLEE to unlock table.
For option 2
Go to SE11. There enter the name of your lock object and create it. Next screen you have to mention which field you want to lock.
For more info. on LOCK OBJECTS go to
http://help.sap.com/saphelp_nw2004s/helpdata/en/cf/21eea5446011d189700000e8322d00/content.htm
If you want to lock the entire table, then use the FM said in option 1 in DO-ENDDO loop.
Run the loop till it gets successful (sy-subrc = 0)
DO.
*Call the FM.
IF sy-subrc = 0.
EXIT.
ENDIF.
ENDDO.
If you want to just try some number of times rather than keep on looping then can use for eg: DO 100 TIMES.

Ora-04021 timeout occurred while waiting to lock object

Hi
Identify the session that is using this object, kill it and then perform the ALTER table... or wait until the session that is accessing this table release it.

JDAPI Error: ORA-04020: deadlock detected while trying to lock object

I have written a JDAPI program to perform read-only impact analysis and report any problems.
The following error is occurring:
"A deadlock among DDL and parse locks is detected.
This deadlock is usually due to user errors in the design of an application or from issuing a set of concurrent statements which can cause a deadlock.
ORA-04020: deadlock detected while trying to lock object /NSPC6/CHECK_FOR_FORM_CHANGE"
The error refers to a procedure in a PL/SQL library.
In one case the error occurred after my final "end of processing" message, which is followed only by a call to "Jdapi.shutdown()".
Any ideas?
Thanks,
Neville Sweet.

Unable to delete Transport Request which contain locked objects

Hi all,
I need to delete some unusable transport requests but as they contain locked objects, it's not possible to delete them. Release operation is just allowed. After releasing these transport requests, I can not find them any more in queue. Please help to find these transport requests which are released and also provide a solution to delete instead of releasing them.
Thanks in advance,
Sanaz.

Hi,
Thank you for the reply.
1. What do you mean by transport request , Shipment Request, Shipment Order or Tour.
A. I mean requests which can be transported between SAP Systems using TMS (Transport Management System).
2. What are the objects which has been locked and due to that you are facing this problem.
A. There are diffrent object types. For examle some customizing have booen done or SAP Note correction has been implemented, ... Therefore some objects have been locked due to these operations
3. Let's say if it's an freight Unit, then Pls confirm that System dump / error is not the cause for this.
A. I have no idea about "Freight Unit".
Thanks,
Sanaz.

Placing multiple page PDF as anchiored objects in text

I am trying to place a multilple page pdf as an anchored object in text. Ideally I'd like it to flow in and size to the column width. Is this possible? Im running ID 5.5 on windows 7. Ive tried the script for MultiPageImporter-but I cant seem to get it place the pdfs in text. Any ideas?

If you use the mutlipage importer to import the PDF into a New Document that has the same width as your text frame (perhaps a bit smaller).
Then Export that to PDF from InDesign.
You should now have a smaller PDF.
Then in your document you want to place that PDF choose File>Place and select the New PDF you created.
Make sure the Show Import Options is ticked.
Import all the Pages.
You now have to manually place the PDF into the document into the text to anchor them.
If you need to do this automatically I suggest visiting the Scripting Forum - forums.adobe.com/community/indesign/indesign_scripting

Anchored Objects with text wrap, need vertical space

Hi. I'm a fairly new InDesign user and have just this past week learned about anchored objects, threading text frames, numbered lists, and some other fun options. So far InDesign has done most everything I need fairly elegantly. However, I have not been able solve one issue.
In my book I have numerous pages that have this issue; I'll just describe one case. On this page there are 4 graphics running down the right side of the page. These are not anchored graphics. They do have text wrap defined on the left side and bottom. There is text that wraps lovely on the left.
Each of these four graphics has a specific paragraph it needs to top align with. However, the text it aligns with may not take up as much vertical space as the graphic does. When I anchor each graphic with the paragraph it needs to align with, the four graphics overlap each other.
At the moment, to make it look right, I have placed each graphic individually and added a blank paragraph above each paragraph of text that should align with a graphic and use the Space Above of each blank paragraph to have it align with the graphic.
I'm not even sure what to search to try and solve this. I looked briefly into compound paths, but that didn't look like it would help.
I hope this is clear and thank you for any assistance at all.

No problem. Click your cursor somewhere in the paragraph that ought to be aligned with the next image down, then run this Javascript.
It's not entirely accurate, as it uses the font size to do a minimal adjustment where it actually should use the font's cap height -- but you cannot get to that through scripting. This final adjustment is necessary because ID does know the baseline, and your first line ought to dip just below this to have the top of the first line aligned to the top of the image.
//DESCRIPTION:Align paragraph with image.
// Jongware, 15-Jul-2010
if (app.selection.length == 1 && app.selection[0].hasOwnProperty ("baseline") && app.selection[0].paragraphs[0].index > 0)
 // find nearest image on the right
 ypos = app.selection[0].paragraphs[0].lines[0].baseline;
 pg = app.selection[0].parentTextFrames[0];
 while (1)
 if (pg instanceof Character)
 pg = pg.parentTextFrames[0];
 if (pg instanceof Spread || pg instanceof Page)
 break;
 if (pg instanceof Document || pg instanceof Application)
 exit(0);
 pg = pg.parent;
 img = pg.allGraphics;
 dist = 999999;
 nearest = null;
 for (i=0; i<img.length; i++)
 if (img[i].geometricBounds[0] > ypos && Math.abs(img[i].geometricBounds[0] - ypos) < dist)
 dist = Math.abs(img[i].geometricBounds[0] - ypos);
 nearest = img[i];
 if (nearest == null)
 alert ("no image found nearby!");
 else
 prevm = app.activeDocument.viewPreferences.verticalMeasurementUnits;
 app.activeDocument.viewPreferences.verticalMeasurementUnits = MeasurementUnits.POINTS;
 top = nearest.geometricBounds[0];
 ypos = app.selection[0].paragraphs[0].lines[0].baseline;
 if (ypos < top)
 app.selection[0].paragraphs[0].spaceBefore = top-app.selection[0].pointSize-app.selection[0].parentStory.paragraphs.previousItem(app.selection[0].paragraphs[0]).lines[-1].baseline;
 app.activeDocument.viewPreferences.verticalMeasurementUnits = prevm;
This image shows three paragraphs aligned with their respective images (it won't work on the first paragraph, but that ought not to be necessary anyhoo).
