You want to define the number of failed login attempts allowed before the user account will be locked. In a User Storage System scenario like ‚ABAP only‘ or ‚UME and ABAP‘, this is controlled by the underlying AS ABAP Server.

In case the UME has a user storage AS ABAP, its own policies doesn’t apply but only the one of the AS ABAP server.

Depending of the ABAP component SAP_BASIS

this can be defined either in the ‚profile parameters‘ (SAP_BASIS before 7.31) or in the ‚Security Policy‘ (SAP_BASIS 7.31 and higher).
ATTENTION: In case of SAP_BASIS lower 7.31 there is no possiblitly to define different settings for internal users and WCEM users.
In case your AS ABAP system runs on a version SAP_BASIS 7.31 you can easly influce the ‚Security Policy‘ for WCEM users without modifying SAP standard coding.
First you need to create a new Security Policy using transaction SECPOL.
Now, depending on your AS ABAP system, either CRM or ERP, you can use the following injection locations for your coding.
CRM: function module COM_BPUS_INTERNETUSER_CREATE import parameter IS_LOGONDATA -> SECURITY_POLICY
ERP: form ‚create_su01_user‘ in function group WEC_USER using parameter p_wa_logondata -> SECURITY_POLICY
In both cases use the implicit enhancement spot (for more details please see here: http://wiki.sdn.sap.com/wiki/display/ABAP/How+To+Do+Implicit+Enhancement) at the beginning of the coding unit to set the security policy relevant for WCEM users.
Now while registering a new user for WCEM your security policy for this user will be applied.
