You want to know if system has limitation or recommended number of line items in CRM documents (Sales orders, Service Orders, Contracts, Quotes, ...) when you create it manually / via excel upload / via migration / via webservices.
Reproducing the Issue
System does not work reliably (dumps/times out) if number of items in CRM documents exceed more than 100 items.
For better performance and reliable system behavior the recommendation is 100 line items or less. Creating documents with more than 200 items is strongly discouraged as the system performance degrades as more items are added. Less than 200 line items would be better for performance and follow up processes to run smoothly.
