What is chain-Endchain in module pool programming?
chain-endchain. When this command is used, all of the fields on the screen that belong to the processing chain (all of the fields listed in the field statements) are made ready for input again. Other fields are not ready for input.
How do you program a module in pool programming?

What is the use of chain and Endchain?
CHAIN and ENDCHAIN define processing chain in SAP ABAP Dynpro Flow logic. User can execute FIELD and MODULE between CHAIN and ENDCHAIN. Also, the statements between CHAIN and ENDCHAIN form a processing chain which cannot be nested.
What is the use of chain and Endchain in ABAP?
The statements CHAIN and ENDCHAIN in the dynpro flow logic define processing chains. The statements FIELD and MODULE can be executed between CHAIN and ENDCHAIN. The statements between CHAIN and ENDCHAIN form a processing chain. Processing chains cannot be nested.
How do you validate screen fields in module pool?
Click on the Top Red button and provide the table name as ‘SPFLI’ and then click on the ‘Get from Dictionary’ button. Select the fields that you want to display in the screen and then click on the Tick button to continue.
What is the use of chain and end chain?
How many PBO events are allowed for a screen?
two events
PBO and PAI are two events used for designing the screens in SAP ABAP Module Pool Programming. Every Dynpro screen has a set of PBO and PAI modules.
What are buffer techniques?
The three main I/O buffering techniques are:
- Single buffer: when data is stored in a section of the system memory.
- Double buffer: allows for two buffers to be used.
- Circular buffering: uses a priority-based queue for when more than two buffers are needed.
What is buffer and its types in SAP ABAP?
The buffering type determines which data is loaded from the table to the SAP buffer when a table entry is accessed and buffering is switched on. The possible buffering types are: Single record buffering.
What is the chain endchain method?
The Chain endchain method is a way of input checks in dialog modules. CHAIN. FIELD: , ,… MODULE . FIELD: , ,… MODULE . ENDCHAIN. When this command is used, all of the fields on the screen that belong to the processing chain (all of the fields listed in the field statements) are made ready for input again.
What happens when a module appears within a processing chain?
Whenever the MODULE statement appears within a processing chain, even if there is only one FIELD attached to it, all of the fields in the chain (not only the affected field) are made ready for input again, allowing the user to enter new values.
How to overcome chain and endchain statement is used in flow logic?
To overcome this problem Chain And EndChain Statement is used in the Flow Logic of the screen where Input fields are validated. Step 1. Go to SE38 , Provide Program name and click on Create Button. Step 2. Provide the title description and choose Type M Program and click on Save Button.
How do you define a processing chain?
You define processing chains as follows: CHAIN. ENDCHAIN. All flow logic statements between CHAIN and ENDCHAIN belong to a processing chain. The fields in the various FIELD statements are combined, and can be used in shared conditions. CHAIN. FIELD: , ,… MODULE ON CHAIN-INPUT|CHAIN-REQUEST. FIELD: , ,…
