Relationship between Form, Datablock, Canvas

What is the relationship between these items?
Since now, to me, a form seems to be synonymous with canvas. As for datablock, i dont know what this is. It seems to be a collection of fields.
Would anyone care to clarify?

A datablock is a collection of fields. If not associated with a database table, it is called a control block, and all the fields in the block are used for miscellaneous purposes within the form.
When the datablock is associated with a database table, it is called a base-table block. Most of the fields in the block represent columns in the table, but you CAN include non-database-table fields too. When you issue a query, Forms automatically retrieves the columns from the database table, and displays the data from the columns in the fields in the block.

ONE-to-MANY relationship between tables and forms in APEX

I recently started using APEX and I have run into an issue.
I have a ONE-TO-MANY relationship between two tables, A1 and A2, respectively.
A1:
A1_ID
Item
A2:
A2_ID
SubItem
A1_ID
I have 2 forms (lets call it F1 and F2) that I use to capture data for A1 and A2.
On F2, I have the following fields that are setup to capture data:
A2.A1_ID
**A1.Item (this is a drop down that is populated using a SELECT statement where the select uses A1.Item field)
A2.SubItem (user would enter SubItem)
Note: A2.A2_ID is populated using a SEQ
Everytime I pick **A1.Item on F2, is there a way to link to A1 table and display A1.A1_ID for every **A1.Item selected on F2?
If so, I want to store the value captured in F2 for the A1_ID field into A2 table to maintain my 1-to-MANY relationship.
If this will work, how do I go about implementing this solution?
Can someone help me?

I think it sounds like you are asking for a Master-Detail form. Try that and see what you get.

Relationship between WebDynproContext and Interactive Form (WebDynpro ABAP)

Hi,
I created a WebDynpro application including an interactive form. The context of the view contains a node 'Employeeinfo' with a further node 'Employeerecords' and a Attribute pdfSource. The node Employeerecords contains 2 Attributes: Employeename and Position.
the structure looks like this:
CONTEXT
___Employeeinfo (node)
______Employeerecords (node)
_________Employeename (attribute)
_________Position (attribute)
______pdfSource (attribute)
Employeerecords should be used as a table with the columns Empl.-name and Position. The Content of this table is filled by a Supply-Method.
I bound the properties of the interactive form like this:
pdfSource-> pdfSource
datasource-> Employeerecords
The Interface of the interactive Form is XML created by Context of the webDynpro Component.
When I start the application it is showing me an empty form allthough the Content was created correct by the Supply-Method ( I tested this with a WebDynproTable element in the same View). The table seems to be there ( I check this with a seperate color) but the Rows are not created.
It seems to me that there would be no relationship between the WD-Context and the Interactive Form.
Do you think it is a design mistake or a software problem?
I work with the following software components:
AdobeLifeCycleDesigner 7.1
Adobe Reader 7.0.9
SAP NW 04s
SAP GUI 6.4
ADS is working fine.
Could you please help me?
Thank you,

Relationship between XML Forms

Hello,
I have 3 XML Forms, Macro Process, Process and SubProcess. The 3 xml Forms must have a sequential id (like a tree structure). For example: I created a Macro Process with Id=1, when I created a Process I have to associate this Process with a Macro Process and it has and id of 1.1 (The Process is associated to Macro Process 1). If I created a subprocess this have to be associated to a Macro Process and a Process and it has an id of 1.1.1 (Macro Process Id=1, Process Id=1.1). Every forms that is created with the 3 Xml forms must have the following structure
1 MacroProcess1
--1.1 Process1.1
1.1.1 SubProcess1.1.1
1.1.2 SubProcess1.1.2
--1.2 Process1.2
1.2.1 Process1.2.1
2 MacroProcess2
--2.1 Process2.1
2.1.1 SubProcess2.1.1
This type of relationship can be done with xml forms, I can validate that the id that introduces the user is correct and it is not repeated, How can I do that? How can I visualize this 3 XML forms preserving the relationship between Macro Process, Process and SubProcess?
Thanks in advance for your help

Hola Teresa,
Mira tuve un problema similar y no lo pude resolver.
Se que podes meter codigo en el form y resolver este problema.
Es necesario para vos usar el Form Builder ? si tu respuesta es no porque no usas el Visual Composer, haces una conexion contra una base de datos y esto no deja de ser un simple ABM. Otra alternativa es que desarrolles usando el Developer Studio.

Creating a relationship between one table and the PK in another

Sorry the subject of this message is a bit vague. I'm not sure how to describe this problem in one sentence.
So here's the issue: I've just created a new block on my form based on table2. Table2 contains t1_id which is the FK link to Table1.
What I want is when one of the fields in Table2's block is changed and inserted, the t1_id is inserted in the applicable row. Essentially, I need :table2.t1_id to have the 'Copy From Item' property set at :table1.id
I cannot seem to see where in designer this option is. I asked a friend and he said what I need to do is 'create a relationship between the two values in designer'. Huh? In the Table Definitions the FK is set for the two, so I'm not sure how to do this.
Another problem, which I'm believing will be solved when this is, is that when the form loads, this new block, table2, is not automatically populated with the applicable values from the table.
Thanks for any help. It's greatly appreciated!

Do you mean that you want to create a Master-Detail Form using Designer?
If yes, you need to define the entity usage from the Function Hierarchy Diagrammer, then attribute usage definition. Generate the module using Application Design Transformer. You need to define the Context so that master table's PK will be carried over to the detail table.

Relationship between Dynamic Memory Heap and Heap Data Structure

This question is not strictly related to Java, but rather to programming in general, and I tend to get better answers from this community than any where else.
Somehow, my school and industry experience have somehow not given me the opportunity to explore and understand heaps (the data structure), so I'm investigating them now, and in particular, I've been looking at applications. I know they can be used for priority queues, heap sorts, and shortest path searches. However, I would have thought that, obviously, there must be some sort of relationship between the heap data structure, and the dynamic memory heap. Otherwise, I can think of no good reason why the dynamic memory heap would be named "heap". Surprisingly, after searching the web for 90 minutes or so, I've seen vague references, but nothing conclusive (trouble seems to be that it's hard to get Google to understand that I'm using the word "heap" in two different contexts, and similarly, it would not likely understand that web authors would use the word in two different contexts).
The Java Virtual Machine Spec is silent on the subject, as "The Java virtual machine assumes no particular type of automatic storage management system, and the storage management technique may be chosen according to the implementor's system requirements."
I've seen things like:
[of dynamic memory] "All the blocks of a particular size are kept in a sorted linked list or tree (I extrapolate that sorted tree could imply heap)"
[of dynamic memory] "The free and reserved areas of memory are maintained in a data structure similar to binary trees called a heap"
[of dynamic memory] "This is not related to the heap data structure"
[of dynamic memory] "Not to be confused with the data structure known as a "heap"
[of data structure] "Not to be confused with the dynamic memory pool, often known as TheHeap"
At this point, I've come to surmise that some (but not all) memory management algorithms use heaps to track which (pages? blocks? bytes?) of memory are used, and which are not. However, the point of a heap is to store data so that the max (or min) key is at the root of the heap. But we might want to allocate memory of different sizes at different times, so it wouldn't make sense to key on the amount of available memory in a particular region of the free store.
I must assume then that there would be a different heap maintained for each size of memory block that can be allocated, and the key must have something to do with the attractiveness of the particular memory block in the heap (perhaps the lowest address, resulting, hopefully, in growing the free store space less often, leaving more space for the stack to grow, or perhaps keyed based on the fragmentation, to hopefully result in less fragmentation, and therefore more efficient use of the memory space, or perhaps based on page boundaries, keeping as much data in the same page as possible, etc).
So at this point, I have a few questions I've been unable to resolve completely:
1. Am I correct that the heap was so named because (perhaps at one point in time), a heap is/was commonly used to track the available memory in the free store?
2. If so, would it be correct that there would be a heap per standard block size?
3. Also, at what level of granularity would a heap typically be used (memory page, memory blocks, individual words (4-bytes))?
4. What would be the most likely property one would use as a key. That is, what makes the root item on the heap ideal?
5. Would a industrial strength system like the jvm use a (perhaps modified or tuned) heap for this sort of task, or would this typically be too naive for an real world solution today?
Any insight would be awesome!
Thanks,
A.

I think you are not only mixing terms but domains.
For starters the OS allocs memory. Applications, regardless of language, request memory from the OS and use it in various ways.
There are many variations of the term "heap" like the following.
[http://en.wikipedia.org/wiki/Heap_(data_structure)]
[http://en.wikipedia.org/wiki/Dynamic_memory_allocation]
A java VM will request memory from the OS (from a 'heap') and use it in its application 'heap' (C/C++) and then create the Java 'heap'. There can be variations of that along the way that can and likely will include variations of how each heap is used, potentially code that creates its own heap, and potentially other allocators which use something which is not a heap.This last part, I find a bit confusing. By "use something which is not a heap", do you mean the heap data structure, or the dynamic memory pool meaning of heap? If the former, then you would be implying that it would be common for a heap data structure to be used to manage the heap dynamic memory pool. If the latter, what would this "something which is not a heap" be? The best definition of "heap" I've found simply states that it is a pool of memory that can be dynamically allocated. If there is some other way of allocating dynamic memory, then it would suggest that the previous definition of "heap" is incomplete.
>
So to terms.
1. Am I correct that the heap was so named because (perhaps at one point in time), a heap is/was commonly used to track the available memory in the free store?Which 'heap'? The VM one? It is probably named that because the implementors of the Sun VM were familar with how C++ and Smalltalk allocated memory.Okay, but that begs the question, was the heap in C++ and/or Smalltalk so named for the above queried reason?
>
2. If so, would it be correct that there would be a heap per standard block size?Not sure what you are referring to but probably a detail of the implementation. And since there are different levels the question doesn't mean much.
However OS allocations are always by block if that helps. After that it requires making the question much, much more specific.
3. Also, at what level of granularity would a heap typically be used (memory page, memory blocks, individual words (4-bytes))?Again not specific enough. A typical standard implementation of heap could not be at the word level. And it is unlikely, but not impossible, that variations would support word size allocations.
The VM heap might use word boundaries (but not size), where the application heap certainly does (word boundary.)My understanding of it is that the application would request blocks from the OS, and then something like malloc would manage the memory within the allocated blocks. malloc (or whatever equivalent Java uses) would have to keep track of the memory it has allocated somehow, and I would think it would have to do this at the word level, since it's most commonly going to allocate memory at the word level to be references to other objects, etc.
So I guess my question here would really be, if the dynamic memory heap is so named because there has been a memory management strategy that relied upon a heap data structure (which I've found no proof, but have found some suggestive literature), then would that probably have applied at the OS Page Fault level, tracking allocated blocks, or would that have applied at the malloc level, allocating individual words as necessary?
>
4. What would be the most likely property one would use as a key. That is, what makes the root item on the heap ideal?"Key" is not a term that will apply in this discussion.
You appear to be referring to strategies for effective allocation of memory such as allocations from different regions by size comparison.
It is possible that all levels might use such an allocator. General purpose applications do not sort allocations though (as per your one reference that mentions 'key'.) Sorry, I got the term "key" from an article I read regarding heaps, that indicates that a "key" is used to sort the elements, which I guess would be a more generalized way to make a heap than assuming a natural ordering on the elements in the heap. I'm not sure if the terminology is standard.
>
5. Would a industrial strength system like the jvm use a (perhaps modified or tuned) heap for this sort of task, or would this typically be too naive for an real world solution today?Again too indefinite. The Sun VM uses a rather complicated allocator, the model for which originated after years of proceeding research certainly in Smalltalk and in Lisp as well, both commercially and academically.
I am sure the default is rules driven either explicitly or implicitly as well. So it is self tuning.
There are command line options that allow you to change how it works as well.I guess perhaps I could attempt to clarify my initial question a bit.
There is a 1:1 correspondence between the runtime stack, and a stack data structure. That is, when you call a function, it pushes a stack frame onto the runtime stack. When you return from a function, it pops a stack frame from the runtime stack. This is almost certainly the reasons the runtime stack is named as it is.
The question is, is there or has there ever been a 1:1 correspondence between some aspect of the dynamic memory heap or how it is managed, and a heap data structure? If so, it would explain the name, but I'm a bit puzzled as to how a heap data structure would be of assistance in creating or managing the dynamic memory heap. If not, on the other hand, then does anybody know where the name "heap" came from, as it applies to the dynamic memory pool?

What is relationship between ping and tcp in BGP ?

Dear All, As we know, BGP peer relation needs reachability of tcp 179. But usually if the two peer neighbors can ping each other, we can consider the tcp 179 is working well. So what is relationship between ping and tcp in BGP in this situation ? Thank you !

Ping is a tool in the ICMP suite, and doesn't use ports. It uses codes. TCP is a different protocol, and does use ports. In the case of BGP, once the process is started (and you have at least one neighbor command) it will open port 179. Who is the client and who is the server in the neighborship, does not matter. If you have issues with BGP neighbors being formed, and you believe the configuration is correct - Telnet to the port to be sure that it is working. Also, if they are not directly connected, you may need to enable multihop. Check Access lists also.
Pinging the other router it is unrelated to the BGP TCP process. - Here is an example pinging fine, but before the BGP process has opened port 179.
There is just two routers on a /30 segment - 10.19.2.2 and 10.19.2.1
LON-ROUTER#ping 10.19.2.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.19.2.1, timeout is 2 seconds:
Success rate is 80 percent (4/5), round-trip min/avg/max = 8/9/12 ms
Pings fine.
LON-ROUTER#
LON-ROUTER#telnet 10.19.2.1 179
Trying 10.19.2.1, 179 ...
% Connection refused by remote host
Enable BGP on the neighbor:
LON-CORE(config)#router bgp 65000
LON-CORE(config-router)#neighbor 10.19.2.2 remote-as 65001
LON-CORE(config-router)#
try the TCP connection again
LON-ROUTER#
LON-ROUTER#telnet 10.19.2.1 179
Trying 10.19.2.1, 179 ... Open
The connection now works, as the port is open on the neighbor.

Relationship between Contracts Core module and other contract modules

Hi,
I am wondering the relationship between contracts core and related modules like Project contracts, sales contracts, procurement contracts and service contracts. Are they related, I mean if I want to create a project contract in projects do I need to have a core contract created in Contract core module, is this contracts core module is same Contracts module of CRM.
When I tried to develop some reports in Project contracts module in past I noticed the project contracts information is not available in one applications like OKE, it has to be taken from contracts core and contract projects database schema tables ( OKC ).
Please help me in understanding the whole scenario with respect to contracts created in various modules. Is it mandatory to have a contract created in Contracts (CRM ) module first and then the contracts in various applications?. What is contracts Core module? If I try to create a contract in Projects or any other module I will have a workbench to do it but that workbench could have been a collection of forms registered in various other applications including contracts core module in that case it becomes difficult to single out which tables it is interacting with as in many cases they are views.
Please give me a clear picture. I tried to get it from various user/implementation guides but things are not very clear. I am a developer but need to understand these procedures.
Thanks in advance,

ERMS - how to find relationships between e-mails?

Dear all,
I'm working with e-mail management and I'd like to know if there is a way to find relationship between e-mails.
Let's assume an e-mail is sent: the workflow for the same is created and an entry appears in the Inbox.
Now, let's assume the customer writes a new e-mail in the same e-mail chain, to add some details (or answer to our reply): a new workflow is initiated and a new e-mail is available now in the agent inbox.
Is the system able somehow to recognize that the two e-mails belong to the same chain? For operators, it would be important to know that, to avoid double processing of customer requests.
When I use role IC_MANAGER an use the e-mail workbench, I see that in the second e-mail the linkage to the first is identified, but when the same reaches the inbox I was not able to find any useful field to identify this information.
Anybody with experience on this?
I'll reward points if you can help!

Error while adding a used relationship between the New DC and the Web DC

Hi Gurus
We are getting the Error in NWDS while Adding a used relationship between the New DC and the Web DC.
Steps what we are Done
1. Create the custom project from inactiveDC's
2.creating the project for the component crm/b2b in SHRAPP_1
3.After that we changed the application.xml and given the contect path.
4.Then we tried to add Dependency to the custom create DC we are getting the error saying that illegal deppendency : the compartment sap.com_CUSTCRMPRJ_1 of DC sap.com/home/b2b_xyz(sap.com.CUSTCRMPRJ_1) must explicitly use compartment sap.com_SAP-SHRWEB_1 of DC sap.com/crm/isa/ like that it was throwing the error.
so, we skip this step and tried to create the build then it is saying that build is failed..

Hi
Please Ignore my above message.
Thanks for ur Response.
After ur valuble inputs we have added the required dependencies and sucessfully created the projects, then building of the projects was also sucessfully done and EAR file was created.
We need to deploy this EAR file in CRM Application Server by using the interface NWDI.
For Deploying the EAR into NWDI, we need to check-in the activites what i have created for EAR. once i check-in the activites ,the NWDI will deploy the EAR into CRM Application Server.
In the Activity Log we are able to check the Activities as Suceeded but the Deployment column is not showing any status.
When i right click on my activity Id the deployment summery is also disabled.
So finally my Question is that where can i get the deployment log file, and where can i check the deployment status for my application..
Any pointers in this regard would be of great help..
Awaiting for ur valuble Responses..

Relationship between Portal and back-end roles in business package

Hi all,
I wonder how technically works on the backend system when I install a BP for SAP EP. Let's say for example that I installed on the portal the business package for SRM. I will have on the Portal some roles configured (buyer, supplier, invoice manager, etc), and some iviews in them organized by pages and workest.
How can I see the relations with those roles and the roles on the SRM backend system? And then: if I modify a standard role on the Portal, adding new functionalites (iviews), I do update the backend role? We are going to implement SSO, and users will be the same on Portal and backend system. But that also means I need to assign users to backend roles on the backend system, isn't it?
I would be glad to you if someone can provide me also a link to a document explaining the relationshipe between backend roles management and portal roles management.
Thanks a lot,
Valentina

To add.. no, you will not update a backend SRM role if you update an iView on the Portal. The Backend roles will always be assigned to the user via PFCG and do not change automatically with the Portal roles.
This help document might help you understand the concept better (Look at the Permissions vs Authorisations section):
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/c605c690-0201-0010-e8b5-94677245a46b
Hope this helps. I am sure SAP/SDN library has many such documents that you can read through.
