列名称无效＆＃39; PaymentRecommendationId＆＃39;即使列存在于表中？

Question

这是在添加额外匹配参数AND PR.PaymentRecommendationId = InputJSON.PaymentRecommendationId)后在更改操作时抛出异常的存储过程：

ALTER PROCEDURE usp_PaymentRecommendationsInsertUpdate
@PaymentRecommendationsJson NVARCHAR(MAX)
AS
BEGIN 
    MERGE INTO PaymentRecommendations AS PR
    USING ( 
                SELECT      ClaimId,
                            CoverageTypeId,
                            Payee,
                            IndemnityPmtRequestAmnt,
                            ExpensePaymentRequestAmnt,

                                    RequestDate DateTime,
                                    Memo VARCHAR(512),
                                    CheckNumber VARCHAR(16),
                                    IssueDate DATETIME,

                            )) AS InputJSON
               ON (PR.ClaimId = InputJSON.ClaimId AND PR.PaymentRecommendationId = InputJSON.PaymentRecommendationId)
    WHEN MATCHED THEN
        UPDATE SET  ClaimId = InputJSON.ClaimId,
                    CoverageTypeId = InputJSON.CoverageTypeId,
                    Payee = InputJSON.Payee,
                    IndemnityPmtRequestAmnt = InputJSON.IndemnityPmtRequestAmnt,
                    ExpensePaymentRequestAmnt = InputJSON.ExpensePaymentRequestAmnt,
                    RequestDate = InputJSON.RequestDate,
                    Memo = InputJSON.Memo,
                    CheckNumber = InputJSON.CheckNumber,
                    IssueDate = InputJSON.IssueDate,
                    ModifiedOn = GETUTCDATE(),
                    ModifiedBy = InputJSON.ModifiedBy
    WHEN NOT MATCHED THEN
        INSERT (    ClaimId,
                    CoverageTypeId,
                    Payee,
                    IndemnityPmtRequestAmnt,
                    ExpensePaymentRequestAmnt,
                    RequestDate,
                    Memo,
                    CheckNumber,
                    IssueDate,
                    CreatedOn,
                    CreatedBy)
        VALUES (    InputJSON.ClaimId,
                    InputJSON.CoverageTypeId,
                    InputJSON.Payee,
                    InputJSON.IndemnityPmtRequestAmnt,
                    InputJSON.ExpensePaymentRequestAmnt,
                    InputJSON.RequestDate,
                    InputJSON.Memo,
                    InputJSON.CheckNumber,
                    InputJSON.IssueDate,
                    GETUTCDATE(),
                    InputJSON.CreatedBy)
    WHEN NOT MATCHED BY SOURCE THEN
        DELETE;
END

以下行导致上述存储过程出错：

ON (PR.ClaimId = InputJSON.ClaimId AND PR.PaymentRecommendationId = InputJSON.PaymentRecommendationId)

错误：Invalid column name 'PaymentRecommendationId'.

但是PaymentRecommendationId列在json字符串中传递以及它存在于表

中
