Change the transaction description for intercompany balancing entries

Hi ​@rena98
Here is how you can implement this logic.
It’s quite difficult to customize this process, since I haven’t found any simple methods to override in order to change the description. But I finally found one that works:

using PX.Data;
using PX.Objects.GL;
using System;
using System.Linq;

namespace MyProject
{
    public class PostGraphExt : PXGraphExtension<PostGraph>
    {
        [PXOverride]
        public virtual Batch CreateInterCompany(Batch b, Func<Batch, Batch> baseMethod)
        {
            var batch = baseMethod?.Invoke(b);

            var trans = Base.GLTran_Module_BatNbr.Select().FirstTableItems
                .Where(t => t.TranDesc.Contains("Balancing entry for:"));
            var descriptions = trans.Select(t => t.TranDesc).ToHashSet();
            var firstDescription = descriptions.FirstOrDefault();
            var lastDescription = descriptions.LastOrDefault();

            foreach (var tran in trans)
            {
                if (tran.TranDesc == firstDescription)
                {
                    tran.TranDesc = lastDescription;
                }
                else if (tran.TranDesc == lastDescription)
                {
                    tran.TranDesc = firstDescription;
                }
            }

            return batch;
        }

        [PXProtectedAccess]
        public abstract class PostGraphProtectedExt : PXGraphExtension<PostGraphExt, PostGraph>
        {
            [PXProtectedAccess(typeof(PostGraph))]
            protected abstract Batch CreateInterCompany(Batch b);
        }
    }
}

FYI: This solution is based on 25R2. If you are using a different version, the code above may need some adjustments. Let me know if that’s the case.
