Picking Request& Goods Issue Numbers

Hi,

I have a small issue, regarding pickig request n goods issue numbers,

wen we see the document flow of completed delivery,

flow will be,

Order--Completed

Delievery-open

Picking request--completed

Goods issue ---Completed,

I would like to know,

<b>how n from where this picking request and goods issue numbers generating?</b>

I have looked into, accounting document which was created after PGI ie, WL-GOods issue doc n observed the number range is 49,but the interval which i have given is different with system generated one.

I observed the picking request number was: the current date ( in YYYYDDMM format),

Can i maintaing my own number ranges for these doc's?

<b> Problem havent solved yet? Any HINT</b>

Points well rewarded
