Hi balasubramanyan,
If you can not find any data through FMB_PL01 it's a signal that there isn't any budget available.
Take a look how the transaction works when there is budget available:
FMB_PL01 you will fill with the following data:
Company: Your Company Code
Commitment Item: TESTCOMMITMENT
Fund Center: DUMMYCENTER
Value Type: B1 (Budget)
Year: 2015
Running this report it returns for me the available budget for this Commitment Item and Fund Center in 2015.
If you system is not returning any data, you must insert budget. Try do that manually through transaction FMBB.
The fields highlighted in red are fields required in our FM scenario, maybe in your company its values and fields may be different; But, you can see at the bottom of the screen the place where we inform the commitment item and fund center and the budget that will be inserted on them.
By the way, I read that you informed you have budget. If it's true, the system should show this information via FMB_PL01 report.
Try to this via FMBB and then run then report again.
If you have any problems, please let me know.
Regards,
Rodrigo
