This process enables the creation of a new mapping format to map additional fields that could not be mapped with the standard target structure.
Note
You can display additional fields in the mapping tool if you have enhanced the structures CRMT_MKTLIST_ORG_EXT, CRMT_MKTLIST_PER_EXT, CRMT_MKTLIST_ADR_EXT, CRMT_MKTLIST_CP_EXT, CRMT_MKTLIST_ACT_EXT, CRMT_MKTLIST_LEA_EXT, or CRMT_MKTLIST_BCI_EXT.
You can append additional fields only to the mentioned _EXT structures and not to the database tables or other structures. If you append any of the listed _EXT structures then the additional fields are available in all the functions of External List Management.
Create an append structure if there is some data in the address file that cannot be mapped to any of the fields available in the standard target structure delivered by SAP.
Assign the append structure to any of the _EXT structures mentioned above.
On activation of the _EXT structure, all fields that have been maintained in the append structure are available to be mapped in the Mapping Tool. These fields are then available in the relevant database tables.
If the CRMT_MKTLIST_ORG_EXT structure is enhanced by the append structure, then the fields of this append structure are available in the database table CRMD_MKTLIST_ORG and on the Organization tab page in the Mapping Tool.
If the CRMT_MKTLIST_PER_EXT structure is enhanced by the append structure, then the fields of this append structure are available in the database table CRMD_MKTLIST_PER and on the Person tab page in the Mapping Tool.
If the CRMT_MKTLIST_ADR_EXT structure is enhanced by the append structure, then the fields of this append structure are available in the database table CRMD_MKTLIST_ADR and on the Organization Address and Person Address tab pages in the Mapping Tool.
If the CRMT_MKTLIST_CP_EXT structure is enhanced by the append structure, then the fields of this append structure are available in the database table CRMD_MKTLIST_CP and on the Person tab page in the Mapping Tool.
If the CRMT_MKTLIST_ACT_EXT structure is enhanced by the append structure, then the fields of this append structure are available in the database table CRMD_MKTLIST_ACT and on the Activity tab page in the Mapping Tool.
If the CRMT_MKTLIST_LEA_EXT structure is enhanced by the append structure, then the fields of this append structure are available in the database table CRMD_MKTLIST_LEA and on the Lead tab page in the Mapping Tool.
If the CRMT_MKTLIST_BCI_EXT structure is enhanced by the append structure, then the fields of this append structure are available in the database table CRMD_MKTLIST_BCI and on the Activity or Lead tab pages in the Mapping Tool
