Certain profiles can't use SalesOrder when MasterDetail Business Map is used

[Guido1982]

I've setup a Business Map that allows for "units delivered / received" in SalesOrders. Works fine for me, but for certain profiles, that have less rights, I get the following when trying to open a SalesOrder:

Code:

Fatal error: Uncaught exception 'WebServiceException' with message 'Permission to perform the operation is denied' in [[SERVER_PATH]]/crm/include/Webservices/DescribeObject.php:25 Stack trace: #0 [[SERVER_PATH]]/crm/modules/cbMap/processmap/MasterDetailLayout.php(206): vtws_describe('InventoryDetail...', Object(Users)) #1 [[SERVER_PATH]]/crm/modules/cbMap/processmap/MasterDetailLayout.php(164): MasterDetailLayout->getFieldInfo('units_delivered...') #2 [[SERVER_PATH]]/crm/modules/cbMap/processmap/MasterDetailLayout.php(98): MasterDetailLayout->convertMap2Array() #3 [[SERVER_PATH]]/crm/modules/cbMap/cbMap.php(472): MasterDetailLayout->processMap(Array) #4 [[SERVER_PATH]]/crm/include/utils/DetailViewUtils.php(1338): cbMap->__call('MasterDetailLay...', Array) #5 [[SERVER_PATH]]/crm/include/ut in [[SERVER_PATH]]/crm/include/Webservices/DescribeObject.php on line 25

I've set the permissions for this profile to allow the use of InventoryDetails module, but without success...
