How JP430000 (processPurchaseOrderV2) sets the next status (F4311.NXTR) when settings the processing options as below?
P43XPI|Version, (Tab) Order Status
1. Beginning Order Status allowed for External Publish = 220
2. Ending Order Status allowed for External Publish = 230
P4310|Version, (Tab) 1 - Defaults
3. Beginning Status = 220
4. Override Next Status = 400
JP430000 does not reference the processing option of P43XPI|version during interop (in this context, interop encompass pure Z File interface, RTE, and business service).
P43XPI|Version, (Tab) Order Status
1. Beginning Order Status allowed for External Publish = 220
2. Ending Order Status allowed for External Publish = 230 --------------- this parameter is related with RSS PO dispatch
P4310|Version, (Tab) 1 - Defaults
3. Beginning Status = 220
4. Override Next Status = 400 ------------- this value is used when you want to override next status so it does not follow order activity rule.
both creation/update of Purchase Order is only affected by P4310|Version. So I guess you do not have to set same value because above setting will set F4311.LTTR = 220 and F4311.NXTR = 400.
