JRC error calling procedure

[former_member262942]

I have a report that uses the sap procedure TMSP_DOCLINETYPELAYOUT. In the report I defined two numeric parameters: DocKey and ObjectId. If I open the preview with Crystal Report, it works fine, but if I load the .rpt with JRC and than export it in PDF, it gives me this error:

Removing the procedure TMSP_DOCLINETYPELAYOUT form the report, the report is exported without problems.

Can anyone help me with this error?

Thanks
