Code refers to the letters and numbers keyed in by users in the field 'Code'. Most items that can be managed by users would have the field 'Code'. In general, codes can be the acronym of the item made but some codes are pre-defined by Qualification Agencies.
Example of codes that requires user to follow the guidelines provided by Qualification Agencies are program codes, course (subject) codes and tax codes.
Please note that it is the user's responsibility to ensure that a code tagged to an item adheres to the guidelines given by Qualification Agencies.
Account codes on the other hand, should be the same with the existing code in user's accounting software. This would ensure that all codes are fixed. This practice should also be implemented for other systems used outside Sqayy.
