question about chain

[Former Member]

hi,

i am looking a program (PAI) and i see

a lot of statements like

CHAIN.

FIELD gs_telling-zuonr_uit5.

FIELD gs_telling-sgtxt_uit5.

FIELD gs_telling-dmbtr_uit5.

ENDCHAIN.

does anyone know if this could have a function without module in it.

If there is any error while doing the PAI...the user should be allowed to contniue with the correction of the record...

It allows user to correct the entry and then proceed.

There fore we use Chain and EndChain..

whatever module we write in chain ... endchain block that is trigerred whenever a field inside the chain statement is changed when re-running the report....

Yes, that part i know.

But can it have a usefull function if there is no module in it?

Thanx in advance.

Hi,

From this code snippet all that can be figured out is that the fields within the CHAIN and ENDCHAIN block are intended for a common processing or individual Module Processing. Generally all the fields within chain and endchain will be intended to be processed with a same module. This is applicable for a general or common error handling or user validation scenario.

But, as the module statement is not present here, i guess the PAI event will be triggered but it will not process anything.

You can have a look at this demo code for the CHAIN ENDCHAIN Keyword from the DEMO Program:

DEMO_DYNPRO_FIELD_CHAIN.

Hope this will help.

Thanks,

Samantak.
