DROP SHIP - EPICOR mis-alignment to PO Lines/ SO Lines, PACK lines.... multi-LOT

In dealing with DROP SHIP… a few discoveries as to EPICOR flagging ‘pending’ lines
Requesting Company PO inter-co results in responding Company Sales Order and PACK
When the PACK LINES do not align, as to line-item and part number on the Sales Order / interco PO
EPICOR will ‘not’ write a record to DROP SHIP DETAIL

Only acceptable/matching elements will result in a record written to DROP SHIP DETAIL
The DROP SHIP screen indicating ‘pending’ items, simply displays un-matched PACK-lines
Subsequently a user must manually correct/add the additional entries for DROP SHIP DETAIL
IF 3rd party invoicing occurs w/o doing so the customer is short-billed!

Issue #1 SHIPPER begins PACK, does something wrong, deletes line 1 of PACK
EPICOR will number the new PACK line as line 2
which no longer aligns to SO LINE #
DROP SHIP DETAIL will not have records written for this PACK
correction - BPM to alert shipper
ISSUE #2 Additional PACK lines required due to Multiple lots being shipped
ex: Lines 1-2-3-4 on Sales Order requiring line 5 & 6 on PACK due to Multi-lot
correction - Method Directive / Data directive… auto-add additional DROP SHIP DETAIL records
processing is exactly what manual user entry to DROP SHIP DETAIL requires
recurring process awakens every 10 minutes during the work day
