A/R invoice and A/R downpayment invoice numbering

Question

Dear Expert
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?
Thank you
Regards
Elton

Problem solved.
After activated 'Permit more than One Document Type per Series' under Company Details -> Basic Initialisation, go to System Initialization => Document Numbering => Relate Series to Document double click the grey box next to Document type and a window of the Series for that particular document type appears. Click New and Numbering Series  - Set up window pops up. Right click to add a row for new series, enter name, required First No. and Next No. for the series. Also, rememeber to define a new Period Ind. for the Primary Series and click Update. On the window of Series, uncheck the box for Primary Series and check the box for the newly created series, click on the number next to the newly created series name to highlight the row and click Set as Default. Finally, click update to confirm the changes and now the document will follow the newly created series.
