The create voucher flag cannot be changed once the document has been changed
When creating a purchase order using Catalina’s API for Dynamics SL and you get the following error:
“The create voucher flag cannot be changed once the document has been changed”
This is getting fired off because of a business rule violation. There is a work around. If you look in your DSLCONFIGFILE.xml, you should look for the following.
<CONFIGITEM ID='DISABLECREATEADONUPDATE' ENCRYPTED='False' COMMENTS=''>TRUE</CONFIGITEM>
Make sure that the value of that CONFIGITEM is “TRUE”. If you don’t have this CONFIGITEM, add it to the site you are using via the SiteID. If you still have the problem after making this change, contact Catalina support to see if there is an update for your version of the API.
