before that we are getting following error messages below

Enter a numeric value ,

Value 000 in field "Posting period" is less than 1

now we have debugged we are getting below

program is failing at the point where it is reading the configuration settings. It is checking if the ledger “0L” is set up for FLEX GL; if not, it is checking for a planning profile since both are not set up in configuration the program is failing.

for that i have checked planning profile in the system using the transaction code GLPLANZ and it is there planner profile as "ZTREKS'"
