Baseline project gantt with parent-child relationship

Hallo,
I'm trying to produce a baseline project gantt like the one I found on: http://apex.oracle.com/pls/apex/f?p=36648:85:997721269859901::NO:::
I want to show planned dates and actual dates using this query:
select null link,
NOME task_name,
ID task_id,
ID_P parent_id,
PREV_START actual_start,
PREV_STOP actual_end,
round(perc) progress,
nvl(DATA_START, prev_start) planned_start,
nvl(DATA_STOP, prev_start) planned_end
from GANTT
but since it looks like it's impossible to show null dates in actual_start I exchanged them so that I have planned dates in the blue line and actual dates in the green one.
It works fine If I have simple tasks but If I have a child, Apex does not display the so called planned line (the green one) anymore, I cannot understand why.
Could you please help me?
Could you suggest me any tutorial about Apex Gantt?
Thank you very much,
Valentina

Thank you VC,
I've already read the tutorial and it's useful but it's only about resource gantt in apex while I'm interested in project gantt.
Hope someone has already done something like this.

Update column with parent child relationships

Hi,
i need to update a column with parent child relationship.
Please provide the possible queries..
Gobi..

Hi,
Depending of the objective and the size of the tables, personally, for maintenance purposes, I preferred duplicate the parent with the new column value and duplicate the child records with this same new value. Other alternative is disable the foreign key temporarily.
You can take a look on this link below too:

Material with Parent Child Relationship

Hi,
Need some advise.
We have this scenario, use purchased materials (.e.g Computer bundle with mouse, monitor and keyboard). We need to track these components separetely at different cost and update inventory with serial no.
Upon creating Sales Order for the above materials, how to we ensure that the full set of materials is picked and delivered. As each components has it own material code.
Is there possible to link up these materials with some sort of parent child relationship? And how to handle it in SAP MM and SD moduld.
Thank you.

Peck,
Unless I am missing something, this is not a Materials Management issue, it is a Sales/Distribution issue.
I think the easiest way is to check the 'complete dlv.' (Complete Delivery) checkbox on the Sales order (VA02>Sales Tab).
When this flag is set, none of the items in the sales order can be confirmed unless all of them are confirmed. All confirmations must be for the same day. No delivery can be created unless all items are deliverable.

Insert Record with Parent/Child Tables doesn't work with Oracle - unlike AC

Hi,
I just Migrated a MS Access 2010 Database to an Oracle 11g Backend with the SQL Developer Tool.
The Migration went fine, all the Tables and Views are migrated.
I'm working with MS Access as Frontend.
The application has some Datasheets with Subdatasheets with Parent/Child Relationship. (1-n Relationship)
After changing to Oracle, it's not possible, to Insert a new Record in a Subdatasheet I always get the following Error Message:
"The Microsoft Access database engine cannot find a record in the table 'xxxx' with key matching field(s) 'zzzzz'"
It used to work perfect with the MS Access Backend, do I need a trigger which first adds the child Record ?
Or what should I do?
Thank you

Hi Klaus,
Thanks for your answer. I still haven't solved my problem. The only way would be to use a singel 1:n Relationship, but in fact I need a n:m Relationship.
I tried the same scenario with a new Access Application, same result.
To clearify my problem.
Goal: Parent Form with Parent Records, Linked Child Form with Child Records in a Datasheet View => Insert of a NEW Child Record.
I have 3 Tables (table1 = Parent tabel, table2 = Child Table, table12 = n:m Tabel with PK and two FK)
The Recordsource of the Parent Form is Tabel1
The Recordsource of the Child Form is Table2 joined with Table12.
In my Old Access Project, Access Triggered the Insert and filled Table12 with the NEW PK of Table2.
It seems like Access can't do that anymore....
I'm pretty desperate and I'm sure it is just a litte thing to fix.....

How to model parent child relationship with DPL? @Transient?

Hello All,
I want to model a parent entity object with a collection of child entities:
@Entity
public class Parent{
@PrimaryKey
String uuid;
List<Child> children;
@Entity
public class Child{
@PrimaryKey
String id;
I know that the DPL won't support automatic persistence where it'll recursively go through my parent bean and persist my children with one call. Is there a way of applying the equivalent to JPA's @Transient annotation on "children" so I can persist the children manually and have the engine ignore the collection?
If not and I want to return to the user a Parent with a List named "children," do I have to create a new object which is identical to Parent, but doesn't have the BDB annotations and manually assemble everything? If possible, I'd like to avoid defining redundant objects.
Thanks in advance,

Hi Steven,
The definition of persistence is here:
http://www.oracle.com/technology/documentation/berkeley-db/je/java/com/sleepycat/persist/model/Entity.html
And includes this: "All non-transient instance fields of an entity class, as well as its superclasses and subclasses, are persistent. static and transient fields are not persistent."
So you can use the Java transient keyword. If that isn't practical because you're using transient in a different way for Java serialization, see the JE @NotPersistent annotation.
In general a parent-child relationship between entities is implemented almost as you've described, but with a parentId secondary key in the Child to index all children by their parent. This enables a fast lookup of children by their parent ID.
I suggest looking at this javadoc:
http://www.oracle.com/technology/documentation/berkeley-db/je/java/com/sleepycat/persist/SecondaryIndex.html
as it describes all types of entity relationships and the trade-offs involved. The department-employee relationship in these examples is a parent-child relationship.

Creating View for a table with parent child relation in table

I need help creating a view. It is on a base table which is a metadata table.It is usinf parent child relationship. There are four types of objects, Job, Workflow, Dataflow and ABAP dataflow. Job would be the root parent everytime. I have saved all the jobs
of the project in another table TABLE_JOB with column name JOB_NAME. Query should iteratively start from the job and search all the child nodes and then display all child with the job name. Attached are the images of base table data and expected view data
and also the excel sheet with data.Picture 1 is the sample data in base table. Picture 2 is data in the view.

I think what you need is recursive CTE
Consider your table below
create table basetable
(PARENT_OBJ varchar(10),
PAREBT_OBJ_TYPE varchar(10),
DESCEN_OBJ varchar(10),DESCEN_OBJ_TYPE varchar(10))
INSERT basetable(PARENT_OBJ,PAREBT_OBJ_TYPE,DESCEN_OBJ,DESCEN_OBJ_TYPE)
VALUES('JOB_A','JOB','WF_1','WORKFLOW'),
('JOB_A','JOB','DF_1','DATAFLOW'),
('WF_1','WORKFLOW','DF_2','DATAFLOW'),
('DF_1','DATAFLOW','ADF_1','ADF'),
('JOB_B','JOB','WF_2','WORKFLOW'),
('JOB_B','JOB','WF_3','WORKFLOW'),
('WF_2','WORKFLOW','DF_3','DATAFLOW'),
('WF_3','WORKFLOW','DF_4','DATAFLOW'),
('DF_4','DATAFLOW','ADF_2','ADF')
ie first create a UDF like below to get hierarchy recursively
CREATE FUNCTION GetHierarchy
@Object varchar(10)
RETURNS @RESULTS table
PARENT_OBJ varchar(10),
DESCEN_OBJ varchar(10),
DESCEN_OBJ_TYPE varchar(10)
AS
BEGIN
;With CTE
AS
SELECT PARENT_OBJ,DESCEN_OBJ,DESCEN_OBJ_TYPE
FROM basetable
WHERE PARENT_OBJ = @Object
UNION ALL
SELECT b.PARENT_OBJ,b.DESCEN_OBJ,b.DESCEN_OBJ_TYPE
FROM CTE c
JOIN basetable b
ON b.PARENT_OBJ = c.DESCEN_OBJ
INSERT @RESULTS
SELECT @Object,DESCEN_OBJ,DESCEN_OBJ_TYPE
FROM CTE
OPTION (MAXRECURSION 0)
RETURN
END
Then you can invoke it as below
SELECT * FROM dbo.GetHierarchy('JOB_A')
Now you need to use this for every parent obj (start obj) in view
for that create view as below
CREATE VIEW vw_Table
AS
SELECT f.*
FROM (SELECT DISTINCT PARENT_OBJ FROM basetable r
WHERE NOT EXISTS (SELECT 1
FROM basetable WHERE DESCEN_OBJ = r.PARENT_OBJ)
)b
CROSS APPLY dbo.GetHierarchy(b.PARENT_OBJ) f
GO
This will make sure it will give full hieraracy for each start object
Now just call view as below and see the output
SELECT * FROM vw_table
Output
PARENT_OBJ DESCEN_OBJ DESCEN_OBJ_TYPE
JOB_A WF_1 WORKFLOW
JOB_A DF_1 DATAFLOW
JOB_A ADF_1 ADF
JOB_A DF_2 DATAFLOW
JOB_B WF_2 WORKFLOW
JOB_B WF_3 WORKFLOW
JOB_B DF_4 DATAFLOW
JOB_B ADF_2 ADF
JOB_B DF_3 DATAFLOW

Reverse Engineering fails to "identify" parent - child relationship

Using Reverse Engineering I obtained two classes - visual compapesence clearly shows that one is inherited from another.
I wish I could copy and paste individual "class Diagrams' for each of those two to demonstrate my point ...
How I could merge those two class diagrams together and "force"
to recognize "parent" <-> child relationship /

On possible solution is to create a diagram in each pacakge that was reverse engineered.
I agree with peter, that a single diagram would not be useful when revese engineering a large project. When diagram get that large, it is hard to see more than a couple of model elements at one time. While we do have the Navigate Link tool, it is still painful to navigate around the diagram. If you printed a diagram that big, it would take up an entire wall.
It is hard to determine what diagrams are needed to explain a software project. For this reason, we have tried to make it easy to build diagrams. Peter, mentioned the first mechanism. Create Diagram From Selected (CDFS) was designed to allow the user to select the model elements that need to populate a diagram. When performing CDFS the diagram will be populated, Relationship Discovery will be executed, and the diagram will be layed out.
Another approach is to create a dependency diagram. You can select a model element, and create a dependency diagram. The contents of a dependency diagram will be the model elements that the selected model element uses. For example, if the model element generalizes from another model element, the super class will be present on the diagram. If another model elements extends the selected model element, the subclass will not be represented on the dependency diagram.
Another diagram creation tool that might be needed is a inheritance diagram creator. An inheritance diagram creator, would make it very easy to see model element super classes, implemented interfaces, and the subclasses.
I hope this helps.

Does table STPOX contain parent-child relationship between components

Hello
I need to get a list of components of SO BOM.
FM CS_BOM_EXPL_KND_V1 exports an output table STPOX.
Does this table contain parent-child relationship between components? If yes , can somebody tell me which fields contain parent child id.
thanks

Hi,
STPOX is not a table, it is a structure & hence there is no storing of data in a structure. The table which stores this info is STPO.
To get the link you can refer to STPO-STLNR & pass this value to MAST-STLNR, this way you can link the child with its parent.

Help needed in retrieving parent child relationship values

C1 10 S1 1
C1 10 S2 2
C1 10 S3 3
C2 20 S4 4
C2 20 S5 5
C3 30 S6 6
C3 30 S7 7
C3 30 S8 8
I want a result of country/state and corresponding code like below.
corresponding states should be displayed under each country with some space appended to it.
Geography code
C1 10
S1 1
S2 2
S3 3
C2 20
S4 4
S5 5
C3 30
S6 6
S7 7
S8 8
I am using oracle 10g version.
Thanks in advance.

Hi,
When you post formatted text (like your output) on this site, type these 6 characters:
\(small letters only, inside curly brackets) before and after each section of formatted text, to preserve spacing.
I think you're saying that you want this output:GEOGRAPHY CODE
C1 10
S1 1
S2 2
S3 3
C2 20
S4 4
S5 5
C3 30
S6 6
S7 7
S8 8
If so, UNION, as Hoek suggested, is a good way.
GROUP BY ROLLUP is more efficient, but harder to understand:SELECT     CASE
          WHEN GROUPING (state) = 1
          THEN cont
          ELSE ' ' || state
     END          AS geography
,      CASE
          WHEN GROUPING (state) = 1
          THEN MAX (cont_code)
          ELSE MAX (state_code)
     END          AS code
FROM     t
GROUP BY cont
,      ROLLUP (state)
ORDER BY cont
,      state          NULLS FIRST
By the way, this looks like a bad table design.
In a relational database, the fact that the name 'C1' belongs to cont_code 10 should only be stored in one place. You have the same information on 3 separate rows.
Also, if 'C1' and 'S1' are both names, they should probably be in the same column, so that (to give just one example) you can find the information about 'x1' without knowing if it is a cont or a state.
A better design would be.NAME     CODE     PARENT     DSCR
====     ====     ======     ====
C1     10          CONT
S1     1     10     STATE
S2     2     10     STATE
S3     3     10     STATE
C2     20          CONT
S4     4     20     STATE
S5     5     20     STATE
C3     30          CONT
S6     6     30     STATE
S7     7     30     STATE
S8     8     30     STATE
If the data is this simple, then the dscr column isn't needed. Whether parent is NULL or not tells whether the rows represents a cont or a state.
To get the results you want from a table like this, you could use CONNECT BY. Using either UNION or ROLLUP, you have to know, at the time you write the query, how many levels there will be in the parent-child tree, and the length of the code is proportional to that depth, and the table has to be changed if you ever need to add another level. CONNECT BY can handle any number of levels, and the length and complexity of the code is the same whether you have just 2 levels (countries and strates), or 7 levels (continents, regions, countiries, states, districts, cities and neighborhoods) or 72 levels. The table doesn't need any more columns, no matter how deep the tree gets.

Parent child relationship is not displaying for IDOC_OUTPUT_ORDERS (PO)

Hi,
Can somebody help me the reason why parent child relationship not displaying properly for ORDER05 basic type?
If we go in details about the problem, a purchase order is creating in R/3 through EBP. To modify my requirement I am using userexit EXIT_SAPLEINM_002. Here I am appending the records in the segment for E1EDKT1 and E1EDKT2. IDOC is creating with an error of status record 26.
When I check in the transaction WE19 for the respective IDOC the data is showing correctly for all the segments including e1edkt1 and e1edkt2 segments and also I check in the table EDID4 segment number is showing correctly and the for the segment E1EDKT2 PGNUM also showing correctly, but when I see the IDOC in the transactions WE02 unable to see parent child relationship between E1EDKT1 and E1EDKT2 segment. Simply the data is displaying one below other like other segment.
I don't know the reason why it is displaying like that?
If anybody is having the solution is highly appreciable.
Regards,
Noorul

hi hassan,
When you are appendng the REcods which belong to the purticular segment..
all the segment needs to be appended in in the proper order as in the WE30..
I think you are appending the segment E1EDKT2 at the end of the EDIDD.. or IDOC_DATA in the user exit.. .. eventho no eerror will be displayed but idoc will generted with sataus 26 .. if check the STATUIs Recored u ewill find the SYNTaX ERROR.
Sollution for ur probelm is... don append the E1EDKT2 at the lastr instead you ahve to insert the segment E1EDKT2. only afer E1EDKT1....
Tehn you r problem will be solved.. I had faced the Same proble when i worked on material maser idoc..
Close this thread if when u r problem ise solved

Parent-Child Relationships in Essbase Studio

In Essbase Studio, I am defining a hierarchy in which a parent member (Wholesaler) is from one dimension table and child member (Rep) is from another. When I preview this hierarchy or build an outline to include it, a few of the Reps that should rollup to a certain Wholesaler are missing. They are not dropped, but Essbase Studio just never recognizes these Reps as being children of that Wholesaler in the first place. However, if I run a sql query against the source data mart with the correct joins, these missing reps do show up in the records of that Wholesaler. Also, the missing Reps are showing up fine in the hierarchy preview as long as I don't make them children of anything in the Wholesaler dim. So Essbase Studio is able to see these Reps, but just can't figure out how they are related to the given Wholesaler. Again, this is only happening for about 10% of the Reps for the Wholesaler. Other Reps are showing up fine in the parent-child relationship.
In the source data mart, I don't see any NULLs or anything amiss in the records for the missing Reps. What other reasons would Essbase Studio not recognize a particular joined record?

it really does sound like a join issue. You say if you just load the children without the parent, they load, but if you associte them to the parent, they don't. You might try when creating the joins to do a full outter join to see if they load and to what.
One other thing you could try would be to create a user defined table that has the join in it. I've found data atype issues in joins from different tables before. Studio is very pickey about this

How to output the outline parent-child relationship using a report script?

I'd like to extract the outline's dimension members with it's parent-child relationship using a report script. Anybody can provide a sample script? Thanks.
Example:
DimensionX
-----MemberX
----------ChildX
Output:
Dimension X MemberX
MemberX ChildX
Edited by: obelisk on Jan 11, 2010 5:16 PM

Sorry a report script won't do it. You have two options
1. Use at Essbase Outline API to walk the outline and get it for you
2. Use the Outline extractor available from Applied Olap (it is a free download). It can be run interactively of as a bat file.
Frankly, I would rather use 2 since I don't have to code it myself

Parent Child Relationships between Drop Down Menus

I have a request for additional functionality. Parent child relationships between drop down lists.
for example,
the first dropdown, could contain North, South, East, West & assign values of 1, 2, 3, 4.
the second dropdown, could contain a filtered set of data depending on the option from the first dropdown,
so the data could look like this in the second drop down:
Manchester 1
Leeds 1
London 2
Southampton 2
Norfolk 3
Newquay 4
so if I select North in the first dropdown, the second drop down would contain all the items with a value of 1, so Manchester & Leeds.
I have managed to get round this using conditional show & hide, but it is much messier on the design screen & also the way in which the data
will be returned is very very messy - seems like a simple addition which would improve the functionality no end.

Question about File Content Conversion and parent-child relationships...

Hello!
 I have read probably every blog, article and SAP Help document on the topic, but I am stuck on this one. I am trying to convert a General Ledger flat file to an IDoc using the classic file --> IDoc scenario. The setup is done and working, but the IDocs are formatted incorrectly and I believe at least part of the reason is how I am converting the file content.
The root of my problem is that the flat file has a parent-child relationship between the document header and the document item and I want to maintain that since the IDoc type (FIDCCP01) has the same structure in the BKPF and BSEG segments.
Here is the flat (non-XML) file layout that is coming into the file adapter:
FileHeader
DocumentHeader
DocumentItem
DocumentHeader
DocumentItem
and so on (until the number of documents is complete
I would really like the content to be converted so that the line items stay under their parent document headers like this:
<FileHeader></FileHeader>
<DocumentHeader>
 <ItemHeader>
 </ItemHeader>
</DocumentHeader>
<DocumentHeader>
 <ItemHeader>
</ItemHeader>
</DocumentHeader>
But I keep getting this, where it lists the document headers first (one after another), and then all of the line items after the document headers like this:
<FileHeader></FileHeader>
<DocumentHeader></DocumentHeader>
<DocumentHeader></DocumentHeader>
<DocumentHeader></DocumentHeader>
<ItemHeader></ItemHeader>
Is is possible to maintain that parent-child relationship from the flat file and pass it over to the XML?
Thanks,
John

Function to get the path using a parent-child relationship

Hello,
I have a table which uses parent-child relationship to store the options available. I need a function to give me the full path given the id of a particular option.
I have two different functions. One of them uses the Oracle built in function and the other uses simple queries with a loop.The code of the functions are given below.
Now, the problem is with their "performance". The difference in their performance is significant. The function using the Oracle function takes more than 2 hours to run a query whereas the other function takes less than 2 minutes.
I am having trouble trusting the other function. No matter how many tests I perform on the output of both the functions, it always comes out to be the same.
Any thoughts to help me understand this ??
Function 1
=====================
FUNCTION Gettree (opt_id IN NUMBER,i_app_id IN NUMBER)
RETURN VARCHAR2
IS
path VARCHAR2(32767);
application_no NUMBER;
BEGIN
SELECT ABC.APP_OPT_ID INTO application_no FROM ABC
WHERE ABC.APP_ID = i_app_id AND ABC.PARENT_ID IS NULL;
SELECT LPAD(' ', 2*LEVEL-1)||SYS_CONNECT_BY_PATH(app_opt_name, '=>') "Path" INTO path
FROM ABC
WHERE app_opt_id = opt_id
START WITH parent_id =application_no
CONNECT BY PRIOR app_opt_id =parent_id;
path := SUBSTR(path,INSTR(path,'>')+1,LENGTH(path));
RETURN path;
END Gettree ;
Function 2
======================
FUNCTION GetOptPath(opt_id NUMBER,app_id NUMBER)
RETURN VARCHAR2
IS
string VARCHAR2(900);
opt VARCHAR2(100);
pid NUMBER(38);
BEGIN
SELECT ABC.parent_id,ABC.app_opt_name INTO pid,string FROM ABC WHERE ABC.app_opt_id = opt_id;
IF pid IS NULL
THEN
RETURN 'root';
ELSIF pid IS NOT NULL
THEN
LOOP
SELECT ABC.app_opt_name,ABC.parent_id INTO opt, pid FROM ABC WHERE ABC.app_opt_id = pid;
EXIT WHEN pid IS NULL;
string := opt || '=>'|| string;
END LOOP;
RETURN string;
END IF;
END;

Hi,
user8653480 wrote:
Hello Frank,
The parameters taken by gettree & getoptpath are app_opt_id and app_id and both the functions return only one string i.e. the path of that particular option (app_opt_id) starting from its root and not all the descendants of that option/root node of that option.
So, does that mean that gettree first fetches all the descendants of the root node of the given option and then returns the required one ??Yes. It's a little like the situation where you need to meet with your co-worker Amy, so you send an e-mail to everyone in the department telling them to come to your office, and then, when they arrive, tell everyone except Amy that they can leave.

And if that is the case, then won't it be better to use the bottom-up approach to fetch the required path just for that particular option ?? 'coz my requirement is that only.. given an option_id get the full path starting from the root.Exactly!
I have used explain plan also for both the functions.. but since I did not know how to anlayze the output from plan_table so I just compared the value in the fields and they were exactly the same for both the queries.If you'd like help analyzing the plans, post them, as Centinul said.
I am attaching a sample data with the outputs of both the functions for the reference.
(tried attaching the file but could not find the option, so pasting the data here)
App_opt_ID     App_ID     Parent_ID     App_opt_name     "gettree(app_opt_id,app_id)"     "getoptpath(app_opt_id,app_id)"
1          1     NULL          application          NULL                    root
2          1     1          module1               module1                    module1
3          1     1          module2               module2                    module2
4          1     2          submod1               module1=>submod1          module1=>submod1
5          1     3          submod1               module2=>submod1          module2=>submod1
6          1     5          opt1               module2=>submod1=>opt1          module2=>submod1=>opt1
7          2     NULL          app2               NULL                    root
8          2     7          scr1               scr1                    scr1
9          2     8          opt1               scr1=>opt1               scr1=>opt1
10          2     7          scr2               scr2                    scr2Please help.The best solution is to do a bottom-up query, and write a function like reverse_path (described in my first message) to manipulate the string returned by SYS_CONNECT_BY_PATH. You seem to have all the PL/SQL skills needed for this.
Another approach is a revised form of gettree, like I posted earlier. Does it do what you want or not?
If you'd help, then post a little sample data in a form people can actually use, such as CREATE TABLE and INSERT statements. Post a few sets of parameters, and the results you need from each set, given the sample data posted.
