​ SAP B1 UPGRADE PROBLEMS 8.81 PL5 to 9.1 PL6

Update from SAP B1 8.81 PL5 to 9.1 PL6, but when performing the test of the base before the upgrade I sell an error in JDT1 without having more information or help note.

Someone who can state the possible reason for that source error in this table and how it could be resolved.

Regards,
