Released Thursday, May 27, 2010 from Sage:
Please be aware that Sage has resolved an issue in the Accounts Receivable module that might be experienced by a specific group of Sage ERP MAS 90 and 200 4.40 and Extended Enterprise Suite 1.4 customers when performing period end processing.
Details on how to discern whether a company has experienced this issue are included in Knowledgebase Entry 524615. The KB entry also includes steps to recover in the event a customer has already performed period end.
Customers who have this mix of open items and balance forward customers in a single company code, should install the fix provided in Support Tip AR4041-T (for version 188.8.131.52) or AR4042-T (for version 184.108.40.206) prior to performing period end. If you are experiencing the symptom described above and Accounts Receivable period end processing has already been performed please call Sage Customer Support.
Please note that single company codes that contain ONLY balance forward customers or ONLY open item customers are NOT affected by this issue.
