Error: Spool request could not be found APOC_OR_MESSAGES 145

Hello guys, I am working with S/4 HANA 1909 and I created an Adobe form for a good receipt PO slip. I put all information in the activity assign template using form type DDIC interface with Z program, Z adobe form, routine ENTRY.

When I create a good receipt, I go to output option and I see all messages and I see the Adobe form correctly generated but when I close the Adobe I get error message SPOOL request could not be found APOC_OR_MESSAGES 145.

I checked by debugging and I found that my Z program ends and I have a SPOOL generated in SP01 transaction and I get SPOOL number, but when the program continues with standard the SPOOL number is empty. I lost the information.

Thanks in advance,

Rubén Martínez and Rosa Rodríguez.
