Field help (ATBEXPLIEN)

This field is only entered if a linked table has been specified. If this field is not assigned, the link is made directly from the field in the current line (which supposes that the primary linked table key is not the only component). In the case where the primary key possesses several components the link expression must be indicated under the form : comp1;comp2;comp;... where comp1,comp2, comp3,... are the components of the key.
Here are a few examples of possible expressions :

 if a field MYFIELD is controlled in one of the miscellaneous tables (for example the table number 43), the value 43 ;MYFIELD will be placed in the column Table linked to the value ATABDIV and in the Link expression column

 if a field MYFIELD is indexed, the expression can use the index variable that can vary between 0 to dim(MYFIELD)-1. Classic examples : the multiple statistics groups (products, suppliers, customers...) whose key structure is the group number followed by a statistics code. The key expression is then written in the form index+1 ;MYFIELD (index).

• If the key component is a global variable, it is necessary to specify the [V] class before the name of this variable.
