The Company Code Restrictions for Maintenance Plants option allows j5 to use the OPTIONS_FOR_COMP_CODE option on BAPI calls to fetch work orders. This can result in better performance on large installations. The value is formatted as first a company code, followed by a colon (:), then a comma-separated list of maintenance plants under that code, followed by a semicolon (;) to separate each company code section.
For example, if you have Maintenance Plants 1000, 1100, 1200 and 1300 under Company Code 1000, and Plant 3000 under Company Code 3000, the configuration will be:
1000:1000,1100,1200,1300;3000:3000
