Error: Unable to retrieve Project Accounting implementation information

Few concurrent request fails when they are submitted using the streamline process.  It is fine when the process is submitted stand alone.

Error would be something like:

"
Using default of 500 expenditure items per set because profile
PA_NUM_EXP_ITEMS_PER_SET is not defined
pasini:BC Profile Option is Not SET.
Defaulting key segment because profile PA_SELECTIVE_FLEX_SEG is not defined
This concurrent request is not being rescheduled
ORA-01403: no data found
                                            
Unable to retrieve Project Accounting implementation information.
pasini() returned error
"

The reason could be:

1> Program 'Operating Unit Mode' should be set to single.

Navigate to 'System Administration' responsibility > Concurrent > Programs
Search your 'Concurrent Program'
Click update pencil icon

Now, in request tab for 'Operating Unit Mode' pick 'Single' and 'Apply'.

Additional 'Operating Unit' parameter in submit request form

2> If you are submitting this MOAC enabled program from back end, operating unit must be set before submit request.

Call
FND_REQUEST.SET_ORG_ID(<org_id>);
before calling
FND_REQUEST.SUBMIT_REQUEST();
