Mapping
ä Mapping is used to create the relationship between our database and the EDI data. For example, if our partner sends us a purchase order number mapping would tell the system where to store the purchase order number in the database. At the same time we could tell the map to manipulate the purchase order number by removing or adding letters, for example. This manipulation of data can be done using a formula or using a data translation table. A formula would be used when the data you are manipulating is dynamic. A data translation table would be used when the data is static. A purchase order number would be considered dynamic because it is always different, therefore if it must be manipulated then you would use a formula. A customer number would be static because they are finite, therefore if the number must be manipulated then you would use a translation table. However, if there is a one to one relationship between your partners representation of the customer number and your internal number you may use a formula to manipulate the number so that it matches yours. For example, if your partner sends you 1000 and your internal customer number is A01000, then you could use a formula to concatenate A0 to the front of the 1000.
