Runtime error PERFORM_INDEX_0 when running payroll simulation

[UdeshiWithanage]

Hey Experts,

I have a problem which is I have created a payroll function starting from Z_ XXX and at the time of activation I don't get any kind of errors and I have added the FORM and ENFORM as well and when click on the source in PE04 it is redirecting me to the correct code location.
But the problem is when running the payroll simulation report (PC00_M99_CALC_SIMU) I get a dump. I have attached the dump SS below.

When further analyzed I found out that the function which I am creating is having an internal number 00 and due to this the code line 13 is giving an error.

Does anyone know why when activating the internal number is picking as 00 and why my function is not showing under the function list in the INCLUDE RPCASFX0?

Found the reason behind this dump! It is because there is a limit of creating custom function for 25 and therefore, in the table T52A0 we have reached the limit FF for the internal number.

I have the same problem with a function. In this case, what was the solution?
