Systems and methods for providing an automated validity check of transactional data postings

A computer-readable medium including program instructions for performing, when executed by a processor, a data processing method comprising:

• entering at least one code for specifying at least one posting to be performed for a transactional data processing operation;
• starting the transactional data processing operation;
• sending a request to a service component for performing a validity check of the at least one code;
• and
• in response to receipt of a first signal indicative of code validity from the service component, sending one or more posting requests with the at least one code to a posting component.

A data processing system comprising:

• a user interface for entering at least one code, the code specifying at least one posting to be performed for a transactional data processing operation;
• an application program for performing the transactional data processing operation;
• means for sending a request for performing a validity check of the at least one code to a service component;
• a buffer memory for buffering one or more posting requests resulting from execution of the transactional data processing operation;
• and
• program instructions for sending the one or more buffered posting requests to a posting component via the network in response to receipt of a first signal indicative of code validity from the service component.

A web service for performing a code validity check, the web service comprising:

• means for receiving a request for performing a validity check of at least one code from a transactional data processing system, the at least one code specifying at least one posting to be performed for a transactional data processing operation;
• means for checking the validity of the at least one code;
• means for generating a first signal indicative of code validity and for generating a second signal indicative of code invalidity;
• and
• means for sending a response to the transactional data processing system carrying the first or the second signal depending on the result of the validity check.
