My client would like the numbering of A/R down payment invoice and A/R invoice fall into the same sequence to fulfill business needs. i.e. After issued of an A/R down payment invoice (e.g. no. 30), then when issue an A/R Invoice, the document number of the A/R Invoice would be no. 31. After that, if another A/R down payment invoice or A/R Invoice is issued, the document number would be 32.
Is it possible? If not, are there any workarounds available?
