help version with multi value

For defining associated MV you should use

XX<ENTE
XX>SISCE.SEC.D

If the definition is correct you will be able to enter data with plain application, no need to define a VERSION.

Multi-valued fields
Any field (except the record id) can be multi-valued. They can be individual multi-valued fields; multi-valued in association with a language code, or part of a group of fields whose multi-values are always in association with each other. Individual multi-valued fields are defined by setting their 'F' table element to 'XX.' followed by the field name, e.g.
F(Z) = ‘XX.NARRATIVE’

Language associated multi-values allow several translations of the value of the field to be held on the record, the appropriate multi-value being used according to the language code of the user. These are defined by setting the 'F' table element to 'XX.LL' followed by the field name, e.g.
F(Z) = ‘XX.LL.DESCRIPTION’

Multi Value Associated Fields
Associated groups of multi-values are defined by setting the third character of the 'F' table to '<' for the first field of the association, '-' for intermediate fields and '>' for the last associated field.
= 'XX<CURRENCY'
= 'XX-CHARGE.RATE'
= 'XX-LOWER.LIMIT'
= 'XX>UPPER.LIMIT'

Sub valued fields
Any multi-valued field can be sub-valued. These can be defined individually or as associations on sub-values within each multi-value. Single valued fields or record ids cannot be sub-valued. Sub-values are defined in the same way as multi-values except characters 4 to 6 of the 'F' table elements are used instead of characters 1 to 3.
= 'XX<CURRENCY'
= 'XX-XX<CHARGE.RATE'
= 'XX-XX-LOWER.LIMIT'
= 'XX>XX>UPPER.LIMIT'
