Function Module to read stack values.

Former Member — Thu, 22 May 2008 09:30:04 GMT

Hello,

Is there is any function module to read the stack values.

My requirement is

I have 3 FM modules say FM_A, FM_B & FM_C.

FM_A will call FM_C.

FM_B will call FM_C.

In FM_C, I need to identify whether the call has been made from FM_A or FM_B without changing these two function modules and by changing only FM_C.

Please help me out.

Thx.

Hi to get the called function module name in FM_C add one more paramter to differentiate the called functionmodule and pass the value while calling the fm_c and check the same in fm_c.

Do award points if usefull

...without changing these two function modules ...

If FM_A & FM_B in ont functional group - no way.

If functional groups of these FM is defferent you can try get any variable from top include.

Need add procedure in FM_C

ASSIGN ('(SAPLxxxx)yyyy') TO <FS>, where

xxxx - function group name

yyyy - variable from top include

IF field-symbol is assigned - FM from this group started our FM.

That's will worked only if new LUW started and modules called by once. Very ugly method and not 100% garanty, but I don't know any else.
