FM to fetch screen data

[Former Member]

Hi all,

We need to know, the existing element list present in a given module pool program and screen number.

Say I give SAPMDEMO_SCREEN_FLOW program and Screen number 0210, I need to get the total element list present, type and size of those elements in that screen.

Does any body have an idea of any FM or any DB table, that would do this, help me out.

Thanks in advance.

Hi,

use

LOOP AT SCREEN.

here you can change the display settings etc.

of each element.

ENDLOOP.

the system will loop through each element of the current screen.

HI

GOOD

TRY WITH THESE FM

DYNP_VALUES_READ Read the values from a dynpro. This function can be used to read the values from a report's selection screen too (Another example).

HELP_START Display help for a field. Useful for doing AT SELECTION SCREEN ON VALUE REQUEST for those fields that do not provide F4 help at the DDIC level.

RPY_DYNPRO_READ Read dynpro, including screen flow

RPY_TRANSACTION_READ Given a transaction, return the program and screen or given a program and screen, return the transactions that use the program and screen.

THANKS

Hi again,

1. RPY_DYNPRO_READ

This is also a good FM.

2. It will give

a) field name, length, position , other flags.

b) it will also give PAI flow logic.
