sorry for late response.
There is special guidelines for this. But certain steps are absolute important.
1. Tracking period and data validity period. as far as my knowladge goes, data of any batch produced must be avaiable until 1 year after the expiry date of product. Especially in case of packed drug product.
2. trackling of batch is absolute important. Yoiu can try EBR in SAp. generally Clients around the worl;d have there own third party system where datats are updated regularly.
3. Since FDA approval is lengthy process and GDP is also a part of Approval, Document flow must be clearly defined, maintained and sustained for defined period.
