Deleting draft documents in draft process

Hello,

I've problem with deleting draft AP Invoices documents in draft process (Approval

Procedure). AP Invoce which i want to delete has status "Rejected"

According to polish help documentation in order to remove such docs i`ve to:

1) From Menu: Administration > Approval Procedures > Approval Status Report - Cancel

an approval procedure, position the cursor on the row of an approval template in the

report results and choose Cancel from the Data menu.

2) Now ,theoretically, i should be able to remove unwanted document from Document

Drafts Report, position the cursor on the row of in the report results and choose

Remove from the Data menu.

Unfortunately after pressing 'Update' i recive 2 contradictory messages:

1) Operation completed successfully [Message 200-48]

2) Cannot delete drafts in approval process [Message 3612-1]

Any suggestions ?

Greetings,

Jedrzej
