Hi All,
Could anyone tell me, Briefly about Indirect Set analysis?? And the benefits and advantages of Indirect Set Analysis over Set analysis.
Thanks and Regards,
Smitha
Have you gone through the help/reference manual? If not, do so. Indirect set analysis is the one that deals with Possible/Excluded values P()/E(). From help :
There is an additional way to define a set of field values by the use of a nested set definition.
In such cases, the element functions P() and E() must be used, representing the element set of possible values and the excluded values of a field, respectively. Inside the brackets, it is possible to specify one set expression and one field, e.g. P({1} Customer). These functions cannot be used in other expressions:
Examples:
sum( {$<Customer = P({1<Product={‘Shoe’}>} Customer)>} Sales )
returns the sales for current selection, but only those customers that ever have bought the product ‘Shoe’. The element function P( ) here returns a list of possible customers; those that are implied by the selection ‘Shoe’ in the field Product.sum( {$<Customer = P({1<Product={‘Shoe’}>})>} Sales )
same as above. If the field in the element function is omitted, the function will return the possible values of the field specified in the outer assignment.sum( {$<Customer = P({1<Product={‘Shoe’}>} Supplier)>} Sales )
returns the sales for current selection, but only those customers that ever have supplied the product ‘Shoe’. The element function P( ) here returns a list of possible suppliers; those that are implied by the selection ‘Shoe’ in the field Product. The list of suppliers is then used as a selection in the field Customer.sum( {$<Customer = E({1<Product={‘Shoe’}>})>} Sales )
returns the sales for current selection, but only those customers that never bought the product ‘Shoe’. The element function E( ) here returns the list of excluded customers; those that are excluded by the selection ‘Shoe’ in the field Product.
Any doubt, let us know.
