Hi
Here are the 1st 2 lines from a working AP Invoice Combined template:
"Company","GroupID","VendorID","InvoiceNum","InvoiceDate","Description",ScrDocInvoiceVendorAmt,"TermsCode","PMUID","TaxRegionCode","APInvDtl#InvoiceLine","APInvDtl#LineType","APInvDtl#PartNum","APInvDtl#Description","APInvDtl#ScrVendorQty",APInvDtl#ScrDocExtCost
"BVD","LANG","LANG","H2199412","10/01/2017","Deliveries on 06-Jan",79.59286,"06EM","6","UK","1","M","ZZ3PT","97217","1",63.93
Youāll need to check things like TermsCodeID, PMUID (Pay method) etc to ensure you set values relevant for your environment.
Also, check that youāve using the latest version of DMT for your version.
Regards
Mark
