Enhancement of MMS

MMS can be enhanced using the enhancement spot /PCH/MMS.

The old function exits are obsolete and replaced by the enhancement spot /PCH/MMS. If implemented, old function exits are still called.

Functions of the ProMaterialData can be extended or restricted by various methods of the BAdI definitions /PCH/MMS_RELATION_DEF and /PCH/MMS_DATA, which both are in the enhancement spot /PCH/MMS.

BAdI Definition	Method	Usage

BAdI Definition	Method	Usage
/PCH/MMS_RELATION_DEF	BEFORE_LOAD_DEFINITIONS	Allows to initialize own data or suppress execution of MMS.
/PCH/MMS_RELATION_DEF	FILTER_RELATION_DEFINITIONS	This method allows filtering of determined control groups. The list of the selection list contains all valid entries, according to the definition, sorted by their priority (smallest value first). After this method only the records with the highest priority will be processed. In case of several valid control groups, it is necessary to consider that this method is followed by the standard checking routine, based on selection rules as described in in the customizing manual, chapter Control Groups.
/PCH/MMS_RELATION_DEF	BEFORE_LOAD_RELATIONS	Called before the relations, based on the relevant control groups, will be determined. The list of control groups can be changed.
/PCH/MMS_RELATION_DEF	BEFORE_LOAD_VALUES	Called before determining the value definitions to be processed. The list of relations to be processed can be changed.
/PCH/MMS_RELATION_DEF	AFTER_LOAD_DEFINITIONS	This method allows cleaning up the determined values for the selected relations.
/PCH/MMS_RELATION_DEF	CHECK_FIELD_VALUES	This method will be called after field value checks supplying the list of erroneous records, which can be altered.
/PCH/MMS_DATA	ADD_COMPLEMENTARY_DATA	This method is called to determine the values for the ProMaterialData Standard Value Handler COMPL:MMS and allows adding additional data. If called with empty list, then this is a search help call within customizing and only the key (FIELD) and description (DESCR) must be filled. MMS uses always a dash ( - ) in its field names (PRM-KNFTP, SY-DATUM, …). Therefore own keys should not use a dash (-). The fields in the table: FIELD “Filter field 1” in customizing VALUE_NEW / VALUE_OLD Value new, respectively old Can be the same, except when used as a trigger for the relation definitions and value must be changed to activate the trigger DESCR Description of the field, used in search help in customizing
/PCH/MMS_DATA	BEFORE_UPDATES	For own initializations called just before starting to update material views and classification.
/PCH/MMS_DATA	BEFORE_UPDATE_MAT_VIEWS	This method is called just before the actual update of material master data with ProMaterialData. Parameters with ending _U are data to be changed, parameters with ending _I are views to be created newly.
/PCH/MMS_DATA	BEFORE_UPDATE_CLASSIF	This method is called before updating / inserting the classification data. It is called for each class and its values.
/PCH/MMS_DATA	AFTER_UPDATES	This method allows individual actions and updates after a ProMaterialData process.
/PCH/MMS_CTRL	CHECK_MATERIAL_EDIT_ALLOWED	Allows the maintenance of a material master despite open MMS actions. This may be necessary, for example, if updates are made to a material master via interfaces making several calls for a material (several logical transactions). If after one of these updates MMS is set up and further updates are made, this results in an error "The material ... is registered for an MMS action".
/PCH/MMS_CTRL	PROCESS_MMS_MAT_SAVE_EXIT	Control whether MMS should be activated for a material. This is called at the very beginning of the MMS implementation in the Material Save Exit and allows the complete disabling of MMS at this time (e.g. special jobs or programs).
