Soa database column (WORK_ITEM) too small for nested activities ?

Question

Hello all,
we've got a big problem on bpm that it seems to imply that activity names should not be too long or activities should not be nested.
We have a BPM Process (named "Process") with parallel cycle that has an activity that calls a reusable workflow "RwSubprocess" with other activities.
The first activity of reusable workflow RwSubprocess is a call activity to a reusable workflow that executes a send task and a receive task (CPT:chRisp) to a ws exposed by a bpel.
The flows executes all the calls regularly, but when it arrives at the call CPT:chRisp it throws the following error.
It seems that the bpm engine creates a custom_id too big for the column in the db...
Is there a solution for this? We choosed to nest activities since the entire workflow is quite big and we used nesting to try to maintain it readable.

We have faced similar challenges and its know issue with BPM (Value too Large for Column "SCHEMA_SOAINFRA"."TABLE_NAME"."COLUMN_NAME" (actual:XXX,maximum:YYY) (Doc ID 1499966.1)).
Solution suggested from Oracle was  to alter the columns to increase the length. We ended up like this.
ALTER TABLE EPRSBPM_SOAINFRA.WORK_ITEM modify CUSTOM_ID varchar2(1024);
ALTER TABLE EPRSBPM_SOAINFRA.WORK_ITEM modify NODE_ID varchar2(1024);
ALTER TABLE EPRSBPM_SOAINFRA.WORK_ITEM modify SCOPE_ID varchar2(1024);
ALTER TABLE EPRSBPM_SOAINFRA.DLV_SUBSCRIPTION modify SUBSCRIBER_ID varchar2(1024);
ALTER TABLE EPRSBPM_SOAINFRA.BPM_AUDIT_QUERY modify FAULT_TYPE varchar2(1024);
ALTER TABLE EPRSBPM_SOAINFRA.WFTASK modify PARENTCOMPONENTINSTREFID varchar2(1024);
ALTER TABLE EPRSBPM_SOAINFRA.WFTASKHISTORY modify PARENTCOMPONENTINSTREFID varchar2(1024);
ALTER TABLE EPRSBPM_SOAINFRA.DLV_MESSAGE modify RES_SUBSCRIBER varchar2(1024);
ALTER TABLE EPRSBPM_SOAINFRA.CUBE_INSTANCE modify PARENT_REF_ID varchar2(1024);
ALTER TABLE EPRSBPM_SOAINFRA.BPM_AUDIT_QUERY modify SCOPE_ID varchar2(1024);
ALTER TABLE EPRSBPM_SOAINFRA.BPM_CUBE_TASKPERFORMANCE modify SCOPEID varchar2(1024);
